Renting equipment for benchmarking

[Tim Callaghan]

Are there any companies in the area that will "rent" servers by the
day our hour?  Every few months I need to benchmark my companies
software on leading edge hardware (like the new Xeon 56xx and 75xx
series processors), but we don't want to keep buying new boxes.

I need 3 or 6 of these, install my OS + apps, benchmark, wipe, and
leave.  Four to Eight hours max.

Any ideas/suggestions?
