RackChoice 2U Micro ATX Compact Rackmount 2 x 5.25 Chassis Support ATX PS2 PSU with 120mm Fan on top, USB3.0 with 2.0 Adapter

I've been really impressed with this little server case. I installed an AMD based mini-ITX motherboard and SFX power supply with an ATX adapter frame. With higher quality fans, it runs quietly and met the need as a laboratory based server for running precision fiber optic microscopes and other Windows-based tools.The chassis is made of decent quality and can adapt easily to whatever custom need you have. Makes for a great media, industrial, or general purpose server. You have room for several SSDs and low profile expansion cards. I'll definitely buy again for future projects.

I am giving this 5 stars due to the build quality and the price. That is not to say its not without its flaws, but these are not issues I had to deal with in my build.Good: Price! Quality Build.Cons: A couple of gripes, but any of the changes I would recommended would likely drive the price up beyond its sub $100 price point.Gripe 1.) There are two, 80mm fans at the front. These use Molex adapters (Blah!). I already planned on replacing these with a pair of Artic or Noctua fans for better performance.The location of these fans make it impossible to service them without taking the system apart. They sit between the front vent and the HDD Trays, but tucked under a lip of the front of the case. So to get access to the fans, you would need to remove the Hard DrivesGripe 2.) Same thing with the filter, it is tucked away in an out-of-reach place. My simple fix for this was to remove the foam filter and set it on the outside. The airflow holds it in place but I am going to 3D print a bracket with magnets to keep it there.Meh 3.) Less of a but something to be aware of. The front HDD Trays: This is a shorter chassis (What I wanted) but if you are planning on installing full size HHDs in the Trays, you will have almost zero tolerance between the SATA/Power connectors and your Motherboard. Its VERY tight. If you are going to use SSD's this may not be as big an issue. And if you are like me and not planning on using the trays at all, then hey no issues.I plan on using a couple of 5.25 bay HotSwap HHD Trays from Icy Dock, and there is plenty of room behind those and the Power Supply.Overall, great Case!Pictures:Red Arrow points to where the filter is located between the front and fans. Have to remove HDD Cage as well as Fan Assembly to access Filter, so it was relocated to the outside of the case (Also pictured).Also showing HDD / SSD Clearance.

Pros: vents on top for power supply, racks well if you stack it on another server that's racked in with rails, decent build qualitycons:not much room, I'm currently doing this one with 6 SSDs and it's a little cramped with all the wiring.If you're using more than a single large spinning drive, i wouldn't recommend this chassis.Default fans are kinda cheap, buy 2 80mm Noctua fans they're much quieterhard drive mounts are really built for larger spinning drives, SSDs don't have much mounting options outside of just laying them inside the chassis somewhere

I bought one and really liked it so I bought two more. I use these in my Promox server cluster. The 2u space saving really freed up room in my rack. Love having the 2 5.25" drive bays for hard drive expansion. All in all a great case, just make sure you are buying a micro sized motherboard for this as a full size motherboard will not fit due to power supply placement. I may have to tame those bright blue power lights however!I would definitely buy another!

If you are looking for one of the smallest 2U form factor cases for rack mounting. This is probably one of the best you can get for the price (~$100 at time of writing).Understand that it does come with 4 slots to fit 3.5" hard drives, but if you are running mATX, there is really only room for 2 at the highest point or you run into space issues. Don't expect to run 3 or 4 hard drives in here with mATX. If you use mini-iTX, you will have no issues filling all 4 slots.It is a 15" depth 2U form-factor, so the build space is very limited, but you will get the same experience in any case with that depth. Very precise cable mounting is necessary with this case, so if you are not ready to struggle a bit to route cabling in the case (especially with mATX), then you may want to go for a 17" depth or more.

It's a nice case. Well put together. Not bad for the cost. I would have preferred 6 cover screws instead of just 4. As other people have reviewed, the issue comes when installing the HDDs. I guess this depends on the layout of your motherboard. On mine the right side bracket can't be used at all because the drives will cover the main ATX power header and get in the way of the memory cards. Maybe a single SSD at the top position but no full size drives. To mount on the left I had to put the larger drive at the top. For mounting the smaller SSD, I had to drill new mounting holes to shift it to the left (and then cut the corner off the mounting plate. Everything was in the way of the USB(3) header. Any one who can't make modifications should stay away from this case.
