I did it in 2013 and 2014. I really liked it, but I hated the noise and heat.
Although the heat was great in the winter.
I still have to buy Gpu's probably RX470/RX480 or if cheap RX570/RX580 (better resell value)
I been looking into cooling and found two possible cooling candidates:
ARCTIC Accelero S3 (passive or with 1 FAN) or Arctic Accelero Twin Turbo III.
and some silent 120mm Case fans.
Does anyone have experience with these mining or any other Silent solutions. (undervolt?)
Best cooling and silent solution is mineral oil. Just dump your rig in container with mineral oil. GG
