Rackchoice 4U Rackmount Server Chassis 4x3.5 + 3x3.5 or 2x3.5+2x2.5 Drive Bays EATX/ATX/MATX/Mini-itx Support

Overall: You get what you pay for. In this case (pun intended) you get a very solid and nice-looking 4u server PC case, but building in it is 4/5 difficulty and I recommend only purchasing if you are familiar with PC building since there aren't any real instructions that come with it.*Technically* I could fit 11x 3.5-inch HDDs, but realistically 6 is about what you'll be able to get in unless you have a motherboard with SATA adapters that don't interfere with the second drive cage. I used a bunch of sata cables with right-angle plugs to help with clearance.The fans are not great, but when else are you going to use the MOLEX power cable that came with your PSU? I'm 3-d printed an exhaust duct so the CPU cooler goes straigh out the back instead of recirculating in the case. I'm just running TrueNAS right now with minimal plugins so the CPU load is minimal and not having thermal issues, but I want to prepare for more demanding CPU loads.Speaking of, I fit a normal ATX power supply in it, but the modular cables might interfere with the cables plugged into one of the 4x3.5-inch hdd cages. I made it work, but it was tight. If you have the option for a shorter power supply overall length, I would go with that.The CPU cooler height is limited. Copy/paste "Thermalright Assassin X120 Refined SE CPU Air Cooler" into your search for a cooler that just BARELY meets the height limit. I think it might be the best bang/buck cooler that fits in it.I'm running a old Z390 mobo w/ 6 3.5-inch HDDs and a couple SSDs for ZFS cache with zero issues, other than putting it all together.

First, I just want to send safe this case is pretty decent for the price. It's cheap and you can tell where they cut the corners at and where the money goes to. The way its setup it's almost like a disposable case unless you are building in it the same way every time.So, that that out of the way here's my thoughts for the build I was going for.I wanted to build a rack mounted remote gaming server. Something to use moonlight or steam link to play games in different rooms in my house without dragging a computer to every room. Or without every room needing a computer in it.I have a i7 13700k, MSI pro z799-s wifi ATX mono, MSI rtx 3080 z trio, MSI MPG A850G PSU, and a Arctic freezer iii 360mm AIO.After removing both HDD cages, and the mounting bar from the top of the case everything fits in this case almost perfectly.This case has 3 120mm fans mounted to a bracket for front air intake. The 360mm rad fits this bracket perfectly. The holes where the fans mount to do not line up with the radiator though. The fans are spaced more apart on the bracket than they are on the rad. You can get only 1 fan mounting point to line up so I used the middle fan mount to attach the rad to the bracket with 4 short rad screws. This supports it enough and keeps it centered perfectly. After mounting the bracket with the radiator and fans on it in a pull configuration. There is just enough room for my 323mm RTX 3080 to fit. We are talking maybe 3-5 millimeters of space. This case also comes with 2 60mm fans ( not sure why the weird size) that are powered via molex. I replaced those with 60mm fans with 4pin pwm. So everything fits, it's tight but works. I have this now installed in the 25u 2 post floor standing network rack in my MDF ( network room) with my 4u NAS and PDU. This case is great my only 2 issues I have with this case is the 60mm fans and that the are those break off kind ( this is where the cut corner is come in) and it doesn't have the attached back thumb screws for easy way to remove the top panel for access inside the case.But, all in all it's a great case and I would definitely recommend if your looking to build a rack mounted gaming setup like I have. You could use it for a NAS but I feel you could buy a different 4u case for cheaper with more HDD bays and easier access.

Great case for large GPUs. My one issue with this is the lack of PWM fans.

Pros: it's relatively cheap, but built pretty well.Decent cooler compatibility. Will fit larger GPUs.I was able to install my 6950xt with pleanty of room to spare.Cons: airflow is not great. It only allows you to mount 2 120MM fans in the front, and 2 60mm fans at the rear. I'd recommend the NF-F12 iPPC-3000 PWM. They are loud when at full blast, but will help mitigate temperature problems.I won't count this as a con, but installing the hard drives requires you to have to remove the drive cage. Swapping out the front fans also requires this.I have purchased two so far. Overall I'd reccomended this case as long as you can get one for $150 or less. Plan on swapping the junk fans that are included.
