>Hi Guys,
>I am running a asp.net written in c# 2005 application. I am about to buy a machine for our SQL Server 2005. Can anyone give me an ideal system configuration. Like CPU, Memory, Disk Size, Raid Type, 32 or 64 BIT. The DB will have about 200 queries a minute on multiple databases with around 120 tables in each DB.

>TIA
