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.

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

This review pertains to the 2U 4-bay case which is presently described as "Support 4X 3.5 HDD Bays and Micro-ATX". This is technically true as long as you don't install all of them at the same time. If you look at the pictures with the 3.5" HDDs in the drive cages both in the description and the data sheet you should notice something I overlooked. That is THERE IS NO CPU INSTALLED. If you install a Micro ATX motherboard with the CPU socket or RAM on the bottom half of the board, even with a low profile CPU cooler it is basically impossible to install 3.5" disks in the two single-drive cages. There is a cartoon in the product literature that is totally wrong because it shows them fitting together like a jigsaw puzzle. The disks will overhang the bottom of the motherboard. Eventually I was able to stuff in 2x 3.5" disks by rotating the leftmost cage and 2x 2.5" SSDs (which BARELY fit above the cooler) but this totally screwed up all my plans which was supposed to have 4x 3.5" disks in this case. You know, per the description and datasheet. Furthermore the wiring to the front panel was frayed and I didn't notice till I had already discarded all the packaging. I did reach out to Rosewill which had very responsive support. That said, the power switches on the front panel are VERY EASILY bumped by mistake. It's a shame because this could easily be a 5-star case with a few tweaks to the design but some really basic things were overlooked. If you do purchase this case for a server and intend to use all the drive cages I would not go larger than a mini-ITX board. Unfortunately with parts so hard to get these days my choices were limited. Overall the build looks nice but I probably wouldn't buy it again unless the design was updated.
