You can built up to 6xgpu mining rig in this chassis/case. But we recommend to use high efficiency cooling fans.
This mining rig chassis can be used to stack in server rack, very comfortable to use. Closed casing is the best for cooling you graphic cards if you use good cooling fans.
This is a nice Mining Chassis mostly because the Riser cards are supported with screws holding them down, It just more support to the Gpu’s.
2nd Psu Mounting sits over the motherboard so not ideal as you need low profile or flexi USB cables. So best configuation is single Psu 1000W + and 6 Cards.
