gonna build one after christmas

my old ones shagged so gonna build myself a shiny new machine

what spec shall i go for given i know nothing about current pcs

not really gonna use it for gaming initially, need to use it for internet, my ipod, music etc, just want to be reliable as my old one crashed all the time

what spec do people have on here

just really asking for advice on what processor and motherboard to go for, all the rest is pretty straightforward

cheers

rory
