Hardware sizing for Navision sql server

Hi, we intend to launch Attain 3.7 at the end of the year. Therefor we are looking for a server system at the moment. Because I’ve got so different informations (2-cpu up to 8-cpu) I’would be grateful for some hints from people with similar environments… Here are some details of our environment: - SQL Server 2000 - Attain 3.7 - 30000 articles - 30000 customers - 500 orders/day with about 3 different items/order I need information about: - number of CPUs - kind of CPU (Xeon, Ithanium…) - size of CPU cache - size of RAM - storage - … Thanks for your replies!
