I'd say you are overly optimistic on the capabilities of Atom processors.
The $199.00 server has 2 3.2GHz Xeons and 4GB ram. It also has excellent
HP smartArray controller and 6 SCSI drives and 2 1GB server class NICs. I
can see how you can get 10 times the performance in a desktop system, but
it seems to run into multiple thousands of dollars, without ECC memory,
without redundant power supplies, without good array controllers, without
SCSI drives ...
I'd look for a refurb 4 processor server, either Xeon or AMD 64bit, put
12GB ECC memory in it, add SATA controller and drives for big slower
storage and let her rip. Desktop systems are just that, desktop. Servers
behave better under load and tend to last better. My $0.02
