I swear i type in invisible text sometimes

The ones that ME and LEEROY put up are ideal.

Pcworld arent that good, yes, BUT the one leeroy put up is very well spec'd for the price, your getting ALOT for your money.

The two you put are no where near as good as the one leeroy put it, so dont bother with those.
If your want one from pcworld then it needs to be core 2 duo and at least 2GBs of ram, and around 200GBs hard drive space.
Or look on the link i provided, that is also a very good make/spec, your getting free delivery AND you'll get £10 change
