any inputs related to configuring a rp7400 are invited. my initial specs based on my current k570 is below.

current k570 (7.3.4)
4 * 200Mhz
2 gn ram

specs for rp7400 (8i/9i)
4 * 550MHz
6 Gb ram

and i thought it was easy.
take a few procs
add ram
add few disks,
(Baaam!) make sound and license
and u hv a server.

but look into a detailed partlist and configuration options at https://www.e-solutions.hp.com/shop/cgi-bin/sweetspot.cgi

Thanks
Mandar
