Never owned a server case before, but I wanted to transfer my mining from my modified Mac Pro so I could have my computer back for normal use.This case is well built and has cut me a couple times when installing the cables. It holds the GPUs very well and has a ton of room all together. The photo I posted doesn't have the fans inside since I'm still waiting on that delivery.Tip: do not use the lid. If you are mining let it be open aired. It's pretty much common sense. Also do not close the front lid, as it pretty much stops air from flowing.

Very good design for the first version. It needs a few small improvements in the GPU area for Riser installations. 6 GPU's are the max for this case. Eight forces the GPUs to sit too close to each other and heat up very fast.

This case is huge...make no mistake!! It's laid out pretty well and is accessible, pity it doesn't come with fans but since it can take 3 x 120mm PWM fans, 4 x 80mm PWM fans, and a further 5 x 80mm 3-pin fans, this thing full loaded will be a buzz fest of note. No matter though, it's a good case and if you get the hercules PSU from Rosewill along with it you'll have power for days!!

Bad design, HDD cage on the side will interfere with PCI slot, no way to install fans in the middle section as other reviewer mentioned. Manual indicates that this should come with fans but it didn't. Case did not fit EVGA SuperNova 1600 which is 225 mm long. WIth unusable mounting section for fans in the middle of the case just taking up space, airflow in this case will be so bad with all the PSU cables (modular, stock) powering 8 GPUs.It may be possible to manage heat if you use 8 blower/reference type cards exhausting heat to front; but then you might have problem managing hot/cold aisle. even if so, the dust filter in the front will interfere with hot air exiting the system. Also, dust filter location indicate that it was intended that air flow from front to back.Lock in the front is completely unnecessary, I'm sure any sane miner would have good physical security of expensive GPUs all in the same placeThis case will simply not work as intended in rack mount, as it will overheat when the lid is put.

Right off the bat when I opened the case I knew this would not work for my GPU setup with 1080Ti FTW3 cards. So I took everything out and put a couple Antminer S9's in it. I have 3 150 CFM fans installed in the front and they are pretty much useless with the front cover up. There isn't nearly enough airflow and even with two smaller fans on the back air trickles out and the has boards get hot. It works find with the front cover down. The top lid/cover is like a cheap baking sheet. When I started to put another server on top of it, the top bowed in and put pressure on the antminers. I had to re-adjust it so the hinge is sticking out on the outside instead of flush on the inside to keep it from caving in. Never seen a server case do anything like that. Bottom line if you have large GPU's like the 1080Ti FTW3, it's not going to work well and can't have anthing sitting on top of the server. I have no idea how you could get 8 GPU's to run cool with the poor airflow but it appears based on other reviews some people have been able to. For me personally, this doesn't work for my GPU's or ASICs. I have resorted to using the case to house a single Antminer that barely gets the job done. :)

So this case I had really high hopes for... It wasn't terrible but here are some things that are really important..1) I chose rackmount because I want this in our DC racks. That being said, the side handles have screws with tall heads, so thick that their clearances won't allow me to rack mount this. I've purchased separate M4 0.7 screws that are not a flat head but chamfered and I had to drill the holes so that they chamfered as well. This is the ONLY way to get it into a rack with both handles on the unit.2) The middle section for fans, simply will not work. It's a great idea, but if you're putting 8 GPU's in this, sorry there's no way in hell you're getting that center fan holder in there.3) The manual has a list of fans for this unit and it's quantities for fan sizes are incorrect. In particular the back of the case needs 1 more fan than it specifies.4) The case has a filter in the front bezel... I get it, it's a rackmount "datacenter ready" case, who want's dust? This is a mining rig, I need as much air flow as possible. Why even ship with it?Construction of the case is very sturdy, parts do not seem cheap at all which I like. It has it's issues but there's not a lot of options out there for mining rigs.

EXCELENTE

For a mining server chassis it's definitely suitable for a beginner setup, it has all necessary dimensions for moderate size cards (take a simple 2080 or 5700XT for reference), and it can hold plenty of small server grade fans for great cooling. The machined parts of the metal seem pretty rough in my opinion, such as the MOBO I/O hole - whenever I try moving cables through it, it grips onto them almost making me worry it'll cut it. Though once the mobo is screwed in this shouldn't be a problem really. Overall, I would get this again since it's pretty cheap and effective. Doesn't seem like it'll break down anytime soon.Also, I believe you can install rails onto it, it has the holes for it, definitely gonna try it out soon.
