rackchoice3U rackmount Server Chassis Support Liquid Cooling Compatibility up to Elevated 360mm Radiator Support SFX PSU/ATX/MicroATX/Mini-ITX MB

Plenty of space, worked well with a 360mm 3 fan radiator. Used an SFF power supply and an ATX board. LP video, SSD bracket, and SFP NIC fit in the slots well.

Most of the other server cases I looked at that claim to fit an ATX motherboard position the PSU in a way that the last few PCIE slots are obstructed. Not sure how other cases can claim to fix a full atx mobo. This case actually fits the ATX motherboard due to the sideways PSU placement. Make sure you have an SFX (small form factor) PSU as it doesn't fit a full size ATX PSU. Perfect for what I wanted and I had the SFX handy. I wish there were a few more options out there that really actually supported ATX without sacrificing PCIE slots. This one was a bit expensive but was the only option I could find.Comes with all the screws needed. Comes with 3x 120mm case fans which I didn't bother to test. They just looked noisy. I replaced immediately with some noctua fans. Space for 2x 60mm fans in the back and Ill probably order some noctuas as well. Single internal cage that looks like it could fit a few hard drives but I just have nvme directly on the mobo so I dont need many. Its just my firewall box.Material is sturdy and heavy steel. Packaging was good and the case had no damage. Aesthetically it looks good. Might buy again if the price comes down - or Ill just start buying MAXT boards with cheaper cases.

Installed asrock mATX b660m rs pro mb with 12900k, ARCTIC Liquid Freezer III 360, and dual rear Bgears b-Blaster 60mm fans. 3x 2.5" sata SSD's in PCI brackets, 1x 3.5 sata in PCI bracket, X520-da2 nic, PCIe to u2 1.6tb nvme drive, 850w SFX power supply, 4tb nvme m2.Run aio and vrm fans at 100%, and rear fans turn on 50*c. Near silent operation. Server and 12900 run cool at 50 to 60*C under FULL LOAD (4.9ghz) for over an hour (after 5.2ghz timeout).Love it uses SFX to allow more in case space! Very good front to rear air flow with no crazy top case holes to plug (so server can be stacked in a rack). AIO was a bit wider than others i guess, so i had to remove 1 front USB plug to make room for the AIO rad. Wanted the 12900k to run at full (and cool, so no thermal throttling) when needed in LESS than 4U - and this case allowed that. photo was taken before sata drives connected. hope this helps someone that is building!!!

As a 3U server case this does not give the compact form of a 1U, nor the roomy bulk of a 4U, it is somewhere in the middle, and sadly, fails to offer the benefits of anything larger or smaller, because while this is large-ish, most of the design space is very wasted. You need an SFX PSU, not ATX, but be careful because the drive tray is VERY close to the PSU mount and long server-style PSU devices might need more depth to fit. You are more likely to do well going with a consumer grade SFX PSU that is shallow enough you won't mind that the drives sit so close behind it.The drive tray holds two 3.5" drives and one 2.5" drive and that is IT. I have seen 1U cases that cram as many as six 3.5" drives in them, but this only has the one drive tray off to the side, and the entire front area is left empty. There are 120mm front fans for powerful cooling, but they are the static 4-pin Molex type so you have no motherboard speed control like PWM offers, and while the face plate of this has nearly and inch and a half of space taken up only by a large dust filter, there is not enough room to mount the fans inside of it, they must mount on the inside of the case area on the motherboard side. If the fans were in that roomy compartment the dust filter lives in, then you could possibly mount your own drive cages on the inner side, and the fans would cool them directly, but you can't, instead the drives are weirdly far off to the side, where the front fans don't even blow on them fully! You just have this large area of space between the fans and motherboard that isn't really used.You could use that space to put in a big, powerful water-cooling radiator, as this is sort of designed for, but what's the point of that when you can't even fit a couple of hard drives in here? Typically they're where all the heat comes from. Unless you are building a very compute-heavy device with huge CPU power and a bunch of graphics cards for AI work you probably don't need that kind of cooling, and if you ARE building such a server, you'll probably just want to go up to a 4U or bigger to accommodate the taller fan mounts/water pipe connectors on high end GPUs anyway.The materials of this are all solid, very strong and impressive, and the overall construction is excellent. I also appreciate that the front panel USB connector is both a USB 3.0 and 2.0 pin-out connector in one, so you can choose which to use it with and the ports just work as whichever revision type they're connected to. Full height PCI-e slots and honeycomb-vented slot blanks you can reuse, not the crummy breakout kind, are even more impressive. I just can't help feeling like the front has so much wasted space, though. Between the cavern-like area the dust filter lives in to the and vast expanse between a typical ATX motherboard and where the front fans are, I just feel like it would have been so easy to use a thin filter with the fans in the front, and a row of drive cages behind them, instead of all of that... nothing. For the 3U of space this takes up on your rack it does not offer the compactness of a 1U, but lacks the actual useful storage space often found in a 4U. If you are building an AI setup that doesn't need much local storage and want to use a big cooling radiator in front instead of the included basic fans, this might just do for you, if your GPUs aren't that tall, but even then, you might still need to go up to a 4U for that kind of added height, because most GPU water-cooling heatsinks send their pipes up from the top, not out from the back, and you would be surprised by how much height clearance they can end up needing.So maybe this is perfect for somebody, but for me at least, the lack of actual usefulness made from all of that extra space just feels really wasted. I keep wanting to go down to 1U, or up to a 4U with lots of real room inside, but this 3U just doesn't really offer anything those other sizes don't, yet it lacks the benefits that make them better choices.

Mounted an ARCTIC Liquid Freezer III 360mm AIO to it. I switched the fans so it was sandwiched between the grill and the radiator. I can see the soft glow RGB rings through the mesh which looks really nice. My temps are great for having a 7950x CPU. I also installed a Noctua NF-B9 92mm fan in the rear using the Noctua NA-SAV4, Silicone Anti-Vibration Fan Mount Set. Overall, I'm very happy with the case quality.
