I didn't hear much back on the tall tophat users as far as a custom or AIO loop. I did a Corsair 120mm AIO --fact it's running right now.
You think a 3070 pcb is short enough to fit?
looks like the PCB itself is. The entire rear fan is just a blow through cut out. I figure with a water block and maybe an undervolt it should be more than fine. Might also just wait for a itx version of it or the 6800 (great call guy above me) but an itx 2080ti on water seems pretty damn appealing to me.
Re the 120mm, it seems like setting the fan to exhaust up through the rad and out the case is the best way to set it up, am I theorizing correctly?
