I was in the process of making the EXACT same thing. For the gpu, a galax 1070 katana (single slot) with the shroud/blower removed and a few noctua A4x10s whacked on the copper heatsink should fit inside the case with no external fan for anyone trying this (undervolt/underclock if the fans arent enough) else you can probably get any thin custom heatsink to fit nicely on any gpu pcb that fits
