Review: Good Case - Fits an Asrock Rack X570D4U, Ryzen 9 5950x + Thermalright Peerless Assassin cooler and a 5090 FE perfectly. Plenty of room for longer PCIe cards, but there really is not enough enough room for power connectors on graphic cards. You will need some right angle adapters on larger cards if the power connector is not already at an angle, like it is on the RTX 50 Series Founders Edition/Pro RTX 6000 cards. There is a support bar that goes across the center, but this was easily removed for space. Included fans are not PWM, but are quiet and functional. Requires two 4-pin molex power connectors for each of the drive bays and the rear fan (7 total), but could get away with a couple of splitters if using SSD's instead of power hungry HDD's. The drive bay power connectors are wired parallel and feed all of the drives (so two 4-pin molex in parallel will feed four drives).
Review: Like these - Some issues - I was looking for some cases for a budget server rack build. I ran across this one. Fit the design, and made by a manufacturer I was familiar with (unlike other manufacturers that just string a bunch of nonsense letters together). Case was decent enough. A couple of quibbles. 1) The cross bar is highly unusable if you are using anything substantial for a CPU cooler. But, it is removable, and doesn't seem to provide any real benefit anyway. I realize this is for GPU bracing, but really, you don't want / need this anyway for that purpose. 2) The intake filter is not easy to get to and kind of defeats the purpose of serviceability. To get this thin, under performing filter out of there to service, you have to literally take the fan bracket out of the case. This is not easy feat. Not sure why no one thought this a problem during design. I personally removed it completely to ensure good airflow anyway. The filter restricts a lot of it. 3) The handles don't seem very strong. Personally, I wouldn't allow the full weight of a built server to be suspended from these handles for any length of time. They likely will crack or break completely. They are good for sliding the case forward for rack removal though. 4) Case came with pre-installed MB standoffs. If you want to thread in more, this becomes an issue. I bought 5 of these cases. And, on each and every one, the extra standoffs (for full ATX installation), were not threaded at all. Which means you have to carefully thread in the standoffs into the unthreaded holes slowly, so they create a thread in the (thankfully) soft aluminum. This works, but geez, why aren't the holes pre-threaded? All in all, good budget rack mount case when money is tight. Just be aware of the pitfalls.

## Features

- Spacious Chassis: This massive 4U server case has 7 internal 3.5” HDD bays plus room for 2 additional 5.25” devices.
- Expandable & ATX/CEB Compatible: 7 PCI expansion slots and ATX and CEB motherboard compatibility give you growth options for all of your needs.
- Quiet Cooling: 3 pre-installed cooling fans provide excellent airflow and heat protection at reduced noise. 1 front 120mm PWM fan and 2 rear 80mm PWM fans ensure your drives and chassis avoid overheating.
- Desired Features: Front panel LED indicators for power and HDD monitoring allows quick, easy visual assessment. Additional utility with 2x USB 3.0 ports and a built-in front panel lock provides extra security for your server case.
