shop bought PCs

I'm moving out into my own place soon and I'm looking to buy a PC to just surf the net, watching anime & listen to music on when I'm off work. I don't have a single clue about building a PC so I just want to go to a store and buy one, any suggestions?

My ideal budget is around £800.

you're foregetting the fact that in UK most distributor just doesn't bother changing the price correctly according to the exchange rate they just reduce the american price by 20% and then slap the pound sign to it
