I had checked out parallelminer for ideas, never really considered buying from them, thinking the shipping would be crazy. But it's $57 to the old continent, pretty reasonnable.
Of course, when you add 30% of taxes on top of the $460, that's starting to be non-negligible...
I wonder if I could run three cheaper server PSUs.
Sure you can

30% tax, damn, that's harsh mate!
