My general opinion about hardware: I rather by for less and more often. performance / price ratio is so rapidly changing so it does not make sense to pay in today's prices for preformance that will be utilized only after 2-3-5 years from now.
The server offered by the manufacturer is around 7K, and my thought was 1 dual xeon 2.33, 4 gb RAM 3X73gb, with 3 year warrenty for about 4.5K. In two years I can throw in another cpu for maybe additional 400-500.
Thanks for help
