Have recently built a machine for just this purpose too, although it runs
Linux, the hardware requirements will be the same.
We needed a huge amount of storage on the network so went for the cheapest
Opteron available (still overpowered), we put most of the cash into a decent
motherboard with gigabit ethernet ports and fast PCI-X 3Ware raid cards to run
the hardrives (the machine has over 3Tb of storage as it's used for video work
- 16x 300Gb SATA drives). Also 1Gb of RAM.
The bottlenecks on a server like this are always the network and drives, so
look at those for performance.
