Sure, anybody can buy them and run them as long as you can meet the power requirements since these will not run on 110v.
Just as a note, you can get a Quick 220 or (if you're really experienced with electrical work) its DIY version. At 800W per server, you can run 3 on a pair of 15A circuits with plenty of margin to spare.I'm lucky, I moved a piece of furniture and rediscoverd a 250v 20 amp a/c outlet only about 12 feet from where the servers are.
