That mobo will do fine, but I'd suggest a higher end CPU for ETH. I've seen several people saying they got CPU limited using a cheapo CPU when mining ETH.
From brief calculations you are about to create 10 or so mining rigs. For PSU I always recommend EVGA, but server type PSU's work with a bit more setup hassle.
For cooling, mineral oil works well, really well if used in conjunction with a ground-loop. This is simply a pipe buried in the ground that circulates water through it. Underground the temp is always ~55F. This 55ish degree water is circulated continuously using a cheap pump and cools the mineral oil res. The mineral oil, now chilled, circulates through your rigs. This setup is reasonably cheap but you need to figure out your thermal load before designing the loop, and consider how much space you have. A horizontal loop is only a foot or two deep, but trenches up a lot of yard getting it set up. A vertical loop requires a deeper vertical hole, but tears up less yard.....and is generally more expensive. You can also cool your PSU's in oil.
Cons: It is a fat burping bitch to clean anything submerged in the oil at a later date. It can be done, but isn't fun, requires chemicals, and takes days.
