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

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).

If you're building a budget-friendly server setup, this Rosewill 3U chassis is a fantastic value. For the price, you get a surprisingly roomy and functional case with 6 internal 3.5" HDD bays—perfect for storage-heavy builds like NAS or home lab servers.It’s made from aluminum, which keeps it lightweight without feeling flimsy. The E-ATX compatibility and 4 PCI slots give you good flexibility for expansion, and the front panel USB 3.0 ports and status LEDs are a nice bonus you don’t always see at this price point.The two pre-installed 80mm PWM fans are a great touch too. They provide decent airflow and stay quiet enough for a home environment.Overall, it's not flashy, but it delivers exactly what you need at a price that’s hard to beat. Great bang for the buck.

Not fancy at all but then again, it's a server, so it does its job perfectly. I fit in an ATX motherboard, Quadro P4000, and a Noctua NH-L9x65 for the CPU cooler and all fit well. The case itself is very sturdy. The only real issue is that the cable management might be a little messy, because you can't remove the panel underneath the motherboard to wire through there.

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.

The height of the standoffs make this closer to a 2U server. Very few GPU’s will fit this case. I ordered two that are worthless. The standoffs are also not removable. This thing is absolute garbage.

So the size of the case is pretty small. I don't care for the engineering that went into this build. I think they could have done a better job at design if they had just given themselves 2 more inches of depth.1. When using the stock Intel CPU fan one of the HDD, second from right becomes useless due to colliding with fan assembly. At first, I removed the pressed in retainers on the HDD cage and that made it better. After thinking about it further I decided to just get rid of all 3 on the right side of the case and went a different direction. With the removal of the cages, I replaced them with a 6, 2.5" backplane that goes into a 5.25" drive bay. I was using 8 SSD drives for the server and decided I liked that 6 would allow me to have access from the front.2. PSU placement. Absolutely horrible design with a major flaw if someone uses a desktop PSU. If you stack this server and have it under load you will take out your PSU as it will not be able to cool down. This, while it would work if you had it on the top rack or if it is just on a shelf with nothing else on it, would allow for cooling, anything that blocks the top PSU vent will cause damage. Rack mounting does not give enough room for this type of design so keep that in mind when considering this case.3. Power and reset buttons, wow, horrible design. Every time I went to power system on while building it caused the plastic power button to stick as the travel allowed it to extend back into the point where it could hang up when popping back out causing the server to shut back down 4 seconds later. My resolve was to take the front panel off and remove the buttons. Now you have to mean to turn on the server or reset it as the buttons are slightly recessed in the case. No one at this point can accidentally shut the system down or reset it as you must get in there just right to access the buttons. I think it is just about right with them removed, a fingernail or hard push will activate them now.If you have no purpose for 3.5" drives and are willing to remove the cages it makes this case pretty good. If you were only using one, the far left it would also work. If you plan on a RAID10 or 5 with 4 3.5" drives just know, any failures to the MB will cause you to fully take the server apart to get to the MB. The screws to access doing this are through small holes that lead down to the screws and reminded me of the game Operation. Going with a small Backplane for storage made this case usable otherwise I would have been sending it back. I would also consider a server-style PSU for this, there are no exhaust fans, which creates a positive air pressure causing a reduction in airflow. I ended up switching fans out and adding one to help cool the SAS controller I used.Hope this helps someone in deciding if this will work for you or not.
