Just for completeness really. I finally decided on;
Pentium 4 3.0 GHz 800MHz FSB with hyperthreading
Asus P4C800-E Deluxe (Canterwood) motherboard
2 x Corsair Platinum TwinX 1024MB DDR XMS3700 CAS3
Thermaltake XaserIII V2000A Alu Case
Globalwin Super Silent 420W PFC ATX Power Supply
Then, because I had my spending head on, I went and forked out more cash for a Wireless Network System;
D-Link DI-624+ Super 54Mbps AirPlusXtremeG+ Wireless Broadband Router
2 x D-Link DWL-G520+ 54Mbps AirPlusXtremeG+ Wireless PCI Adapter
I'm indebted to everyone here for the advice, and also to the staff at Tekheads (www.tekheads.co.uk
) for putting up with my interminable questions!
Now all i have to do is wait for it to get here. I HATE waiting.
