4U Server Chassis 7X3.5 2X 5.25 HDD, Wall Mount Network Rack SL-450A Airflow Rackmount Server Cabinet 7 x PCI Slot Computer Case Lockable with Key Support 80mm Fan, A/V Devices

It is exactly what I thought it would be. Threw my ATX system into it, loaded up all the drives, connected all the cables, closed the case, slid into server rack. 20 minutes to running, exactly like a generic desktop build, no instructions required.This is for home labs and small businesses. It’ll serve those applications well.Pros:It’s rackmount – made for being in a rack. It isn’t getting damaged unless your whole rack is being damaged. It’s therefore functionally immortal and since it adheres to ATX/ITX standards, it’ll never go obsolete. Whatever comes out in the future, there’s a way to adapt it to this. No plastic to break or wear, no proprietary little parts to break. It’s a forever case.Dual fan slot on back should fit many water coolers. I just threw some fans in the spaces but the clearance is pretty good for a radiator’s tubing. The fan grill is also 100% flat on the back, meaning you could mount an extra fan on the outside of each slot.The locking front panel is spiffy. I glued an old used cell phone to the inside as a SCADA display through the hole for the glass and changed the latch to a magnet to keep it closed.Cable management is good – all wires coming out of the PSU can immediately go under the DVD drive bays, down to the HDD bays, and come out exactly where they need to at the motherboard.The front fan pushes air through the HDD bays quite well. My SSDs report no more than 1 degree different between them, and they’re loaded two to a bay, in every bay.I thought I was going to immediately remove the handles but they’re unexpectedly not-terrible. They’ll hold the full weight of my system just fine if I ever need to move it and certainly helped putting it in the server rack slots 5 feet off the ground.The 4U ears add considerable strength against leverage forces and would work in a flimsy network rack without destroying it like a standard 2U chassis could. The drives are very close to the front, adding to good weight management.Cons:Lots of little quality-of-life upgrades/fixes. This is expected with anything at this price point.The included screws are terrible. Spend $3 on an assortment of PC screws or just use the ones from an old case. Some screws are tapered at a weird angle.The rivet holes are of low tolerance so they’re loose. I replaced all the rivets but you could just ignore it.The lid isn’t load bearing. There’s no supporting structural slot for it to slide into at the front, so don’t go putting a monitor on it. I plopped a drill down on it by accident and hand to bend it back up a quarter inch afterwards.The power buttons are momentary rocker switches. The switch labeled I/O is actually the reset, not power. Fixed with a black marker, but if you’re used to standard labels you could physically switch them around.The locking front panel is only held closed by the key lock. If you don’t plan to lock it, add a small magnet to your order and superglue it on. Easy fix.Not a con, but do note that you’ll need to remove the hard drive bays to mount/dismount the hard drives without hitting any of your motherboard components. The lateral stack mounting of the drives is better for cooling but if you want to hot swap things, you’ll need to install an adapter in the 5.25″ bays.Overall:For the $100 price point, this is what you want to buy. It doesn’t have the features you get from premade dell/hp server chassis’ but since it is ATX/ITX compliant, you won’t be locked into their hardware and accessories.
