if someone is interested i can sell cheap open frame made of alluminium
this is the idea, but i have a better design to accomodate 3x140mm fan in front of the gpu, and better security for the psu
selling for 0.1 BTC(around 60 euro) plus shipping
if you are interested i can order more alluminium to make you one in a few days(around 3 day for ordering all parts plus 2 for making it or maybe just one it depend)
