If you're looking for something similarly spec'd you could just buy and beef up a Thinkserver TS440. They are pretty inexpensive, have 8 bays for drives, Xeon E3-1225 v3 proc, ECC memory, redundant power supply (only comes with on slot populated), and start off under $500.

And, in this case, who offers a truly UK cloud IaaS product? All of the key players are American.
