I have seen those around, they would work great with small cards like 1060's and I think I may do my next rig with one. 8x1060's would be a very low power draw rig and wouldn't produce too much heat. It would also nearly match my 8 card 280X based rig in hash rate pretty easily. I have also been sent a breakout board from the USA to test with a small form factor server PSU I have, if that works. This would be a really good cheap rig for selling to people who have solar power on low payment feedback tariffs.
