Custom PC Specification - Decent Enough? Help

[Siggy19]

When I lived in Blighty, I bought a Gateway 2000 computer from the US... not much of a problem. Sure, there was VAT to pay, but it was still considerably cheaper than getting anything remotely equivilent locally. The main annoyance was that it took a few weeks, but then that's the price you pay for the price you pay !
