Triangular computer case

This is a complete PC case that is open and triangle. Made to fit a ATX motherboard and power supply. There are mount to put fan in the front, back and bottom. Also fit AIO in the front It can also fit big graphic cards (one picture show it with a 4070) You would need to buy 6 20mm x 20mm aluminum extrusion 30 cm long. you will also need minimum 27 bolts and nut that fit in the extrusion (that doesn't count fan and graphic card mounting) I recommend drop in nut. It make it easier to plan
