Ok my friend is coming back from london and there is problems with the credit card and he is also short of time due to which he cant shop online. So I want to know good computer hardware shops in London which will be open on saturday so that he can shop before leaving to airport.

The shopping list items are:
AMD 2400/2500+ Mobile version processor
Abit Nf7-S ver 2 m/b
Kingstone Ram modules
ThermalTake Extreme Volcano 12 THF(are they good? or should I buy something else?)
Artic Silver 5

Thats it. Those are the Items in the buying list and its really urgent as I need to convey him atleast before friday so kindly help me guys.

thanks.

PS:Right now he is in Liverpool till thursday so any good shops in there where I can find these items?

If he's gonna try shopping in Liverpool, there is a comp shop called Computer Plus ( I think ) down by the Albert Dock. Pretty good. Havnt used if for a while though
