Along with the case’s modularity, it additionally has logos:
The brand new InfiniRail(TM) fan mount is joined by Corsair’s 3D Y-pattern airflow sample, and higher but, Corsair says this case is “50 Collection Prepared,” which is spectacular, as a result of not even NVIDIA was 50-series prepared.

That is the Corsair Body 4000D, and total, we prefer it. It’s an fascinating case. The case is the successor to Corsair’s long-lived and extremely common 4000D (and its 4000D Airflow and 4000X variants) which we first reviewed again in 2020 and even preferred.

Despite the identify, the Body 4000D is a wholly new design, which implies we’ll should say “Body 4000D” each single time we point out it and might’t shorten it to 4000D as that’s a unique case. We suspect a part of the explanation for the similarity is to allow the traditional reuse-the-old-Newegg-listing trick: these 1,000+ five-egg opinions are nearly all for the unique 4000D, not the Body 4000D, nevertheless it will get to share them on the identical itemizing. Corsair additionally sometimes refers back to the “Body 4000 Collection” sans-D, so we may even see a Body 4000X in some unspecified time in the future.
The case ranges from $95 with out followers to the $110 RS ARGB with 3x 120 ARGB followers. It’s focusing on the trendy price range vary.
There is a $100 center step as nicely with followers however no ARGB. Based mostly on dialogue with Corsair, it sounds doubtless that the MSRPs will enhance as a consequence of tariffs, however we do not have laborious numbers for what these elevated costs can be.
The Body 4000D is fascinating as a result of Corsair has gone all out with the big holes within the entrance panel: functionally, they’re near having no entrance panel in any respect.
Corsair Body 4000D Overview
The differentiating issue for the Body 4000D is that it is supposed to be modular, with customers capable of purchase or 3D print alternate parts.

That is reiterated consistently in Corsair’s advertising supplies, together with public weblog posts: “FRAME is all about customization and we now have some thrilling issues on the horizon. Along with components that will probably be accessible for direct buy, We’ve modelled some blanks of the PSU shroud and motherboard tray, so you may obtain […] these from Printables and customise them nonetheless you want.”

The Construct
The rotatable vertical GPU mount is one among three main options that genuinely reside as much as Corsair’s promise of modularity, the opposite two being the PSU shroud and the motherboard tray (which might be eliminated with 4 screws). That is important: with the ability to ultimately purchase or print particular person parts is sweet, nevertheless it does not have something to do with the case’s design. With these three options, we’re snug saying that the Body 4000D is extra modular than a typical case. It is also potential to swap the glass and mesh aspect panels to both aspect of the case, however this would possibly not be helpful till Corsair sells aspect panels individually or introduces extra case SKUs.
The vertical GPU mount is surprisingly fast to arrange: by loosening two thumbscrews across the growth slot covers, the whole set of seven slots might be eliminated and rotated 90 levels. A riser cable can then be put in and supported by two standoffs put in on the floor of the PSU shroud. Utilizing the built-in mounting holes, a most of three vertical slots are usable. Clearly Corsair intends so that you can buy a Corsair riser cable, however if you wish to use your individual, the holes are spaced 122mm aside.
The Body 4000D has old-fashioned pop-out fill and drain ports on the prime and backside of the chassis, which we additionally actually recognize. Open-loop compatibility suits nicely with the modular philosophy that Corsair is pushing.
To date, these items are good. If we’re choosing antiquated hills to die on, paper manuals will probably be one among them:
We would wish to see a paper guide included with the case along with the model on Corsair’s weblog. The good thing about the web information is that it may be up to date; for instance, the web guide now explains what the purpose of the strip of mylar within the accent equipment is, whereas we needed to e mail Corsair (it covers the reverse-connector holes within the motherboard tray after they’re unused). A paper guide can’t be up to date, which is a draw back as a lot as it’s an upside: The upside is that an organization can’t gaslight a buyer if one thing proves incompatible and is retconned. It’s additionally simply extra handy to construct a pc with a bodily guide.
However then once more, possibly Corsair doesn’t deserve paper manuals since its personal digital guide incorrectly lists the screw depend and steps for eradicating the facility provide shroud. With a digital one, they’ll have the ability to make as many errors as they need and the one individuals who will learn about them is everybody who learn this text.

For the document, it’s 3 screws, not 2. And the diagram can also be incorrect.
There’s one other, bigger piece of black mylar within the equipment, however the guide devotes much less clarification to this one, merely saying that when you “don’t need your cables seen by the underside mesh quarter-panel, swap the translucent insert for the color-matched blank-out insert included within the Accent Field.”
The case additionally has a Lian Li-ish strip of mesh air flow under the glass aspect panel and it ships with the translucent insert. For those who set up followers within the two 120mm slots on prime of the PSU shroud, we would advocate eliminating the inserts solely.
The Body 4000D makes use of the so-called “InfiniRail” system. On the entrance of the case, there are two metallic rails that maintain as much as 12 plastic clips. The rails slide out and in for 120mm or 140mm mounting, and the clips slide up and down the entire size of the rails. Technically, the rails can match 200mm followers at their most width, however solely by forgoing the clips and mounting on to the rails.
On the prime of the case, Corsair took the easier method of utilizing a single sliding rail and no clips. The system is extra sophisticated than it strictly must be, however our solely actual grievance is that there are precisely twelve clips included with the bottom mannequin Body 4000D, with no spares in case one breaks.
The one vital fit-and-finish difficulty with our overview pattern was that one of many plastic items of the ball snap fasteners had popped out of the chassis in transport. We have been capable of finding it and put it again, however identical to the InfiniRail clips, Corsair did not present any extras (like another producers do).
As for construct high quality, development of the Body 4000D feels extra delicate than the older 4000 sequence circumstances. That is partly a tradeoff for the extra breathable mesh sample, versatile fan mounting, and detachable parts. All of these items get exchanged for rigidity. Corsair apparently intends to promote Body 4000D parts individually as nicely, however we do not see any on the shop as of this writing.

On the positives for construct high quality, the frilly stamped 3D sample on the entrance panel is far sturdier than it appears to be like. We’ll have thermal outcomes later on this overview, however the Body 4000D’s entrance panel seems extra open than the 4000D Airflow’s (watch our overview) whereas retaining most of its rigidity.
There is a cable cowl on the entrance of the case that may be put in in one among two positions, however as is often the case, we have been solely in a position to make use of it within the ahead place due to the ATX energy cable. The opposite place is best suited to again join motherboards, of which ASUS BTF, MSI Mission Zero, and Gigabyte Mission Stealth have been validated by Corsair to work. The cable cowl is extraordinarily straightforward to take away, requiring solely a single screw, and it is equally straightforward to slot the aspect fan mount from the accent equipment as a substitute. The aspect fan mount is one other function that can grow to be extra fascinating if Corsair introduces a Body 4000X or different variant with a sealed entrance panel.
Cable administration is sweet with tons of velcro straps behind the motherboard tray, however the most effective route for the 24-pin cable is alongside the cable bar, which is not an possibility if the aspect fan mount is put in as an alternative. Entrance I/O cables are neatly sleeved and the entire I/O unit pops off with two screws, so it could have been good to permit alternate mounting areas (like within the O11D EVO), particularly since having the I/O on the backside of the case has grow to be uncommon nowadays. Even nonetheless, we just like the modularity of it. They’re delivering on that.
As for storage, drives might be mounted on two plates, one behind the motherboard tray and one below the PSU shroud. Every plate can mount both two 2.5″ drives, one 3.5″ drive, or one “iCUE LINK System Hub controller.” We’ll have an interest to see whether or not Corsair comes up with a modular resolution to suit extra drives, however for now, that is it.

The default location of the GPU anti-sag arm is on the cable cowl, too far ahead to learn something besides the longest GPUs, particularly if the cable cowl is shifted to its ahead place.

It may be moved a step additional again by utilizing the “mini mount” within the accent equipment, however there is no approach to do any finer adjustment, and it is best to search for a unique resolution when you actually suppose your GPU wants that assist.

Appearances are subjective. For some, a potential draw back of the Body 4000D’s elevated modularity is that it does not have the clear, uninterrupted strains of the unique 4000D circumstances. We’ll go away it at that; you may type your individual opinion.
Corsair Body 4000D Thermals

The $95 base mannequin Body 4000D that we have been despatched for overview did not embrace any inventory followers, so Corsair despatched alongside a pack of three RS120 ARGB followers. We used these followers to match the inventory configuration of the $110 Body 4000D RS ARGB, which is how the case is marked on our charts. Based on Corsair’s spec sheets, the ARGB followers have the identical specs as common RS120s, so these outcomes are additionally consultant of the $100 Body 4000D RS (non-ARGB)’s efficiency.
CPU Full Load Thermals – Noise-Normalized

We’ll begin with noise-normalized thermals when utilizing our hemi-anechoic chamber to ascertain the noise ranges.
Underneath full load with the case followers adjusted to hit our 27 dBA noise normalization goal, CPU temperature within the Body 4000D averaged 43 levels Celsius above ambient, or 47 levels on simply the P-cores. That is a major enchancment over the unique 4000D Airflow‘s common of 49 levels (53 on the P-Cores), however that is to be anticipated for the reason that older case has solely two followers and splits them between the entrance and rear of the case.
Relative to the remainder of the chart, the Body 4000D carried out pretty nicely right here. The Phanteks XT Professional Extremely is comparable in worth and design, nevertheless it cut up the distinction between the Corsair circumstances, with the Body 4000D nonetheless a pair levels cooler. The Lancool 207 (learn our overview) stays the price range case to beat with averages of 41 levels throughout all cores and 45 on the P-Cores, whereas the NZXT H5 Movement 2024 (watch our overview) and Phanteks G400A (watch our overview) carried out equally nicely. The G400A stays tough to search out within the US.
GPU Full Load Thermals – Noise-Normalized

Transferring to GPU thermals below full load in the identical noise normalized check, the Body 4000D averaged 45 levels above ambient, with 49 levels for the reminiscence and 59 for the unshown GPU hotspot. That is one other victory over the unique 4000D Airflow, which averaged 49 levels for the GPU temperature, however once more that is with two followers to the Body 4000D’s three.
The G400A successfully tied the Body 4000D on this check, whereas the H5 and XT Professional UItra did not do as nicely. The XT Professional UItra averaged 47 levels for the GPU, a pair levels hotter than the Body 4000D. The Lancool 207 stays close to the highest of the chart for cooling. To study extra about that one, you may try our Greatest Instances round-up from final yr or our authentic overview for more information on that case’s professionals and cons.
CPU Full Load Thermals – Full Velocity

At full pace, the Body 4000D’s CPU thermal efficiency continues to scale pretty nicely for its worth, whereas the 4000D Airflow falls additional behind. The Body 4000D’s noise ranges and efficiency have been primarily tied with the Phanteks XT Professional Extremely right here, with the Body 4000D averaging 40 levels above ambient, or 43 on the P-Cores. The G400A carried out equally as nicely, however with a decrease 37dBA noise degree to the Body 4000D’s 43dBA, whereas the Lancool 207 stays an outlier with each decrease temperatures and decrease noise ranges, making it quite a bit higher right here than actually most of those different circumstances.
CPU Full Load Thermals – Standardized Followers

The standardized fan check has all the time had restricted usefulness, however this is among the locations it’s helpful.
It’ll assist us consider the Body 4000D’s uncommon entrance panel by evaluating it towards different circumstances with an an identical set of followers and placements together with the 4000D. Common all-core CPU temperature was 40 levels above ambient and the P-Cores have been 44 levels. That is fairly well-matched to established mesh-fronted circumstances like Fractal’s Meshify 2 Compact (watch our overview) and North XL (learn our overview), and very near SilverStone’s latest FARA 514X (learn our overview). The Body 4000D can also be considerably higher than the 4000D Airflow when normalizing to the identical followers, reinforcing Corsair’s enhancements to the chassis design itself.
Irrespective of how open the entrance panel is, although, the followers nonetheless have to tug air by Corsair’s filter as nicely, so it makes some sense that some single-layer mesh designs just like the Lancool 207, Pop Air RGB (watch our overview), and Flux Professional (learn our overview) carry out barely higher right here, though the G400A additionally did pretty nicely with two layers.
GPU Full Load Thermals – Standardized Followers

In the identical check, GPU temperature within the Body 4000D averaged 43 levels above ambient, tying it with a lot of the circumstances we simply talked about (Lancool 207, Pop Air RGB, and Flux Professional), whereas the XT Professional Extremely did unusually poorly with a mean of fifty levels.
As a aspect notice, GPU thermals with the 4000D Airflow have been abysmal on this specific check relative to the remainder of the chart. That differs from what we noticed 5 years in the past utilizing our previous check {hardware}, which demonstrates the worth of retesting these circumstances now that we have switched to new parts and a flow-through GPU design.
VRM & RAM Full Load Thermals – Noise Normalized

As a closing notice, the VR VCC sensor averaged 30 levels above ambient within the noise-normalized check with the Body 4000D. That places it on the cooler finish of what we sometimes see from circumstances, with solely a few outliers just like the Lancool 207 and Flux Professional dropping to the 27 diploma mark.
The identical goes for the SPD Hub common of 24 levels above ambient (which is the RAM temperature), with comparatively few circumstances on the chart dropping under 22 levels. Each these sensors point out regular inside case temperatures.
Corsair Body 4000D Conclusion

Of the present Body 4000D SKUs, the Body 4000D RS at $100 is an honest deal, particularly given how tightly packed the SKUs’ costs are. Going from 0 followers to three followers is price $5, and going from no RGB to ARGB might or is probably not price one other $10. We want Corsair to observe by with extra modular case parts (just like the alternate entrance panels it confirmed within the trailer) to make it actually fascinating, or on the absolute least supply some extra printable recordsdata.

The Lancool 207 stays king by way of min-maxed price-to-performance, however the Body 4000D is an affordable different to price range Phanteks circumstances just like the G400A and XT Professional Extremely, or doubtlessly some Montech circumstances (which we’ll be including extra of to the charts shortly).
As a successor to the present 4000 sequence, we just like the Body 4000D functionally. Among the finer consideration to element components just like the geometric patterns and yellow accents stay, simply with a extra advanced look than beforehand.
Corsair has talked about that it might have to extend costs, however we don’t but have closing particulars on what that quantity could be on this case. We do not encourage panic shopping for, however when you’ve determined that the Body 4000D is the case for you and it is presently in inventory at MSRP, we would not advocate ready round for a reduction. General, it is a job nicely executed by Corsair. It’s a a lot better return to type as in comparison with one thing just like the 6500D (learn our overview) from final yr.
