Review Corsair Frame 4000D Case Review: Lightweight, effective, and right-priced

[Admin]

Corsair’s Frame 4000D promises modularity, but does it deliver otherwise? We test it with Intel’s i9-14900K and Ocypus fans to determine if it performs well.

It looks nice but I went with the NZXT H7 Flow 2024. That is a really nice case and I got it from Amazon for $90.

A case with good performance, what does that even mean? It is a box.

This obsession with temps is totally stupid, it 2025 and nobody over clocks, temps are irrelevant unless you forget to take the peel off the cooler cold plate.

I love Corsair, and I'm not someone who generally cares much about the aesthetics of PC products, but for some reason the 3000D/4000D series has always felt unreasonably ugly. Just can't get past how bad that front grill looks.

I've done some over clocking over the last couple of decades. It's an interesting thing to do if you are into that kind of thing - but, not important to 99% of desktop PC owners. It never made that noticeable a difference - to me.

I remember purchasing my first SSD and upgrading my C:\ drive. Now that was very noticeable.

I just built a new desktop PC with CUDIMMs. I've putzed around with overclocking the memory - but, the difference wasn't noticeable - to me.

I just built a system in one this weekend. It's really good for the price. I wish I had known that the RGB fans included use standard ARGB headers though vs. Corsair's normal headers. I had to swap them out to connect them to a Commander XL hub. I would have bought the cheaper version without fans.

I recently purchased this exact case for my newest build. To say that I'm disappointed in Corsair would be an understatement. I had purchased 2 Corsair cases in the past, which I loved.
This one, not so much. For starters, why on earth did they move the power button to the bottom of the case? This makes no sense, unless you want this behemoth of a case to literally sit on your desktop, which would be insane. So, no reason to change in the first place, and now that they have, it has made the product much worse. There are numerous additional foibles, like no back door to access the PSU. You have to manually unscrew that horizontal panel that sits above the PSU. It takes twice as long as if there were some thumb screws on the back. So again, stupid design with no reason for the change.
The Corsair product designers need to stop huffing paint. My score: 1.5/5

Also, no installation manual for any of their products anymore. Most of the time there's a QR code with a link to a "quick start guide" on their website, which is just useless. There are simplistic drawings for children. I would like a proper manual with diagrams showing me where the cables go and what goes where. Get on that, Corsair, and please see my note above about your employees and their concerning paint-huffing habits.

I purchased a Corsair PC case recently. The thing I dislike is the box on the bottom for the PSU. The box gets in the way and makes it difficult to set things up inside the case. I have a 12-year-old Corsair PC case without the box, and it is much easier to set things up inside.

I guess the PSU box is there for cosmetic reasons? It seems to serve no purpose.

The other thing I don't like is the ventilation holes for side fans. I have never used and will never use side fans.

Also, I have 3 HDDs in my PC case. The latest PC cases have no slots for HDDs and DVD drives.

I purchased a HDD bracket on Amazon and stuck it on the bottom with magnets. I had thought about using Velcro to stick the HDD bracket to the bottom of the case - but the magnets seem to work better.

Oh yeah don't get me started on the lack of HD and DVD drive space. I personally play a lot of disc based, older games, so I have to use a USB DVD drive. Although with the wacky way they designed this case, the DVD drive will either be sitting on the floor in front of the power button, or dangling off the back IO port.
I am concerned that the Corsair product designers have a debilitating paint huffing addiction. They should seek help, and then go back to designing good products that people can actually use.

The Be Quiet Darkbase 901 has slots for HDDs and an optical drive And it is truly modular and can be installed with left or right window configurations. It's also a much higher quality than this one but it costs more as well. Frankly it's worth it.

 

[HardwiredWireless]

oh wow I don't really need an advertisement for the product. I already said I bought it and was dissatisfied. Are you telling me that I am incorrect?

No I'm telling you that you are correct and that you should return the bad product and buy a good product that you do like. That is what I would do in this case. And so with that in mind I was offering you a better option. You're welcome.

 

[thestryker]

The IO placement is definitely a potential negative for this case. I know there can be some benefits for interior design and room, but the case is already bigger than the regular 4000D and is supposedly about modularity so the inability to move it seems like a big oversight.

Overall I think the biggest problem for this case, and quite frankly most in this category right now, is the existence of the LANCOOL 207 and AIR 903. As long as your PSU isn't too long Lian-li probably wins this category, but Montech is a great value.

Controversial Opinion:

For most users, it really doesn't matter. It is a box, and most users a medium sized box with basic ventilation will suffice.

THAT SAID - I've tested a few cases which have particularly poor airflow in them, and if you are overclocking - that can make a big difference. And that's why we test thermal characteristics - for overclockers.

Everyone else should just focus on the features of the case and if it looks nice, maybe also max noise levels if they don't want to manually set the RPM speeds of case fans.

 

[dave.rara66]

NO. After I saw the placement of the ports at the BOTTOM of the chassis on the 1st pic I stopped reading. Just silly

 

[HardwiredWireless]

Can it be configured as left or right window?

 

[nogames]

So a lightweight case with an unknown weight. At least I can't see the number anywhere in the review.

It is too light to be measured.

I too spent this past weekend building a new computer around this exact case. I have been a solid Corsair case fanboy for years, having used Corsair exclusively when building any scratch systems. This case has caused me to rethink that loyalty. Not that this case is inherently bad, it is not. However, I too, like several others have mentioned, was disappointed in the cheapish HDD provisions ( I have been spoiled in the past with their wonderful HDD screwless bays ) to now perceiving that I should be happy that they provided screws to use to hardwire the drives into the case. About as opposite as it can get. Also, as has been mentioned by others " What is up with the manuals that say almost nothing "?? There are a bunch of wiring harness' that flop of a fairly thick harness. The old-school ones are clearly marked "f-panel" and "HD audio", but there are at least 3 others, which has NO id printed on them nor are they shown in the in the huge for no reason case manual. A diagram in the manual simply saying " this is the USB C connector". Instead, I sat reading and looking all over the internet as well as Youtube to see if I had placed it in the right MB socket. I built this rig for a friend, who has not decided which spin of Linux he wishes to install on it, so it sits on my workbench as of yet not turned on. So please keep your fingers crossed for me.... Almost forgot to mention, I too do not know why on earth they were so stupid to move the I/O panel to the bottom of the front panel. I can tell you point blank, just on that alone, I will NEVER buy this case for myself.
