Roswill RSV-L4000C 4U Rackmount 6-8 GPU crypt mining case Bitcoin Ethereum RSV-L4000B

I bought this to install my 6x RX580 GPU setup into a 4 post server rack. I ended up putting in the 5 extra 80mm fans. The RX580'a put off some heat when they are enclosed. I noticed the GPU's furthest away from power supply get the hottest. The cost on these cases was phenomenal. I was able to get free shipping.
