Diodorus-siculus:
I'm a big fan of Novatech having spent perhaps £15,000 with them in the last few years on behalf of friends and family. They are not always the cheapest but their service is excellent and I have never had a problem with quality. I use one of their notebooks and have built a PC using one of the bundles for myself and both are excellent.
Well worth a look!
I used to work for them for 3 years. Service is good there, especially the tech support lines as they are monitored to answer calls very quickly.
BUT I wouldnt buy a laptop from them. I tend to build my own PC's so wouldnt really buy a PC as they tend to use the cheapest boards they can get hold of, it was elite (part of PCchips brand) plus they are assembled by people on minimum wage that have pictures in front of them to help them put the components in the correct place.
So if you know someone wants a cheap PC with no monitor, then they are OK.
If you want a Laptop - go for a Dell !
