Yeah. I remember looking heavily into this for a while until I got all of my miners stable. Every once in a while the power flickers a bit and I'll lose a miner or two. It'd be convenient to be able to reboot them remotely, but it just doesn't happen enough anymore to justify it (for me).
When Bitcoin was in the bubble and mining was absurdly profitable, I was looking at using some relays from controlanything(.com) and wiring the relays to my power outlets. PDUs are *way* too expensive and you can only put a miner or two on one (since most are only meant for a single 15 or 20 amp input). Some of their relay PCBs are expandable also (if you're running a mining farm and plan to keep expanding).
They do make 240V 30A PDU.
Thats a good 5.7KW. You could run 18+ 5970s.
Sadly it isn't worth the investment though. While it may take a while the writing is on the wall. FGPA will completely replace GPU in time. If I thought GPU mining was going to be around for 2-3 years I might consider it.
