Rosewill RSV-Z2850U 2U Server Chassis Rackmount Case, 4X 3.5 Bays, 2X 2.5 Devices, ATX Compatible, Up to 4X 80mm Fans, 1x USB 3.0, 1x USB 2.0, Silver/Black

Great choice for my home network! However, height is almost too short for a standard PSU and I had some issues with the pre-installed fans hitting the dust covers. On the bright side, drive bays are individually removable if not needed which improves airflow!

I replaced all of the internal fans with Noctua 80mm, and tbh...the sound difference isn't that minimal. I ended up reusing the stock fans in different parts of the case. I did two desktop conversions with these cases, and each worked out although the clearance between the onboard sata ports and the fan housing was so short, I had to remove that housing the get insert the sata cables (and I had to use differing directional angular connections (one up, one down) to fit one of the boards in. I managed to fit 8 drives (6 hdd, 2 sdd) in the drive bay area, but the gap between the drive bays and the motherboard enclosure is a bit small...fortunately, I installed a sas card with thin sata cabling (otherwise, they wouldn't have fit). Clearance between the drives and the fan enclosure is also a few mm too small...cabling coming out of the drives bends sharply against the fan grills (they're ultra thin too), and I ended up breaking one of them (finding out after reassembly...sigh). Being gentle helps there. The one real gripe though, is that the psu compartment is too small for all of the psus I have. I got it to fit, but had to take out the mounting bracket as the psu length is an inch or so too long, so it's just wedged in there. The rails come out of the psu and run right into one of the 4 (optional) 80 mm fans, so I could only power the drives and fans off of the two rails that were far enough to the right to avoid that fan. You will definitely need fan grills on all internal fans. The 80mm space in the rear doesn't have mounting wholes...do I used HVAC tape. It might sound janky, but its stable. Zip ties area your friend as well at keeping cabling in order. I also ended up getting a Noctua low profile cooler to replace the typical monster sized desktop ones. I had to bend it a bit to get it to clear the ram, and still fit inside the 2U enclosure. Had to remove the ram heat sync's as well, but that Noctua was so large it covered the ram as well, so...I suppose that's a little bit of a positive side effect. Note to self: never throw away low profile card brackets...the generic ones I ended up using don't really fit the cards. In total, it was worth the conversion, although with a 10G and SAS card installed. Drives are the same temperatures as they were in the desktop case (29c-35c) even under continuous load. It took a lot of hours though to get things in and fitting...taking things apart when they dont fit and re-routing cables. The second time around though had a much more clean looking result. I don't use rails...my rack has three shelves in place as-is, so they're just stacked (bolted, with spaces on the back side for the same clearance I would have gotten with rails) I think I will go for a 3U or 4U next time just for better clearances for cabling, and more GPU options (which I didn't have for these conversions).

Bought the 15.0" 3U model. tl;dr: Cramped clearances, just barely fits, recommend 17.0" model if possible. Front drive bays need a long screw driver to mount/unmount. I installed with an matx motherboard, you will need to screw in the three standoffs that are supplied in the screw bag. Installed two 3.5in drives overtop the 24-pin in one caddy and one over top the SATA ports in the other. 24-pin barely fit, would likely work better with a 90 degree adapter. I recommend plugging in all motherboard cables (Power, Fans, SATA) before re-mounting the 3.5in drive enclosures. I did not with the SATA ports and I payed the price attempting to plug them in underneath the one 3.5in drive, with barely enough room to fit my hand. Also be careful with CPU cooler clearance, the second 3.5in drive overtop the 24-pin had just barely enough space to plug in the cables. Overall build quality is adequate, functional just to slap your parts in and leave it be (except if you need to swap out a dead drive). I would say money well worth spent.

Excellent little case and had no issues with it. Mounts perfectly in a standard width rack that it shares with other rack mount devices. I would definitely like to warn that you may want to use gloves when building in it as some of the metal areas are extremely sharp and will cut you, like serious skin slicing. You have been warned. Great for low footprint computer positioning.

Great 2u case. Only con is the cable for the PSU is really inconvenient
