Buying a computer in Cambridge

Having been in Cambridge for a fortnight, I find myself in need of a (desktop) computer for my room. What would be the best way of buying one here? Computer stores seem to be few and far between in Cambridge. I'm not necessarily looking for the cheapest system I can find, but neither do I want a top-of-the-range one. I think I'm going to buy the parts and assemble it myself, rather than get a complete system.

A few people have suggested online stores instead of going to a shop, but I'd be interested in hearing what people consider to be reputable stores here, online or otherwise.

Thanks in advance.

Try overclockers.co.uk. This thats the website. They have cheap parts and a big message board if you need any help choosing or putting it together. A great help!

Well... thanks everyone, for your replies. On the basis of what has been said, I think I might buy online. I too have read a number of bad reviews of Overclockers, so I will probably avoid them. I more-or-less know what I want, so I don't need too much help in that respect.

Has anyone else had any experience with the online stores Willa mentioned, viz. microdirect or scan? I would be interested in any further comments or recommendations.

Thanks.

I have never had any problems with Overclockers infact I have found their service to be excellent - I have bought the parts for two computers from there as well as other bits and pieces. The forums are really useful and there customer service is generally very good.
My housemate has had some problems with mirco direct. He ordered a graphics card and they sent him a hard drive. He sends the hard drive back and a few days later a graphics card turns up. Then a few days after that another graphics card turns up. However, my housemate was on holiday so when he got back the 2nd card had been at our house for well over 2 weeks.
The stupid thing is that mirco direct didn't even realise one of their graphics cards was missing So my housemate gets back from his holiday and after thinking about it for a few days he sends it back. He still hasn't been payed for the cost of him sending a hard drive and a graphics card to mirco direct.

I have had no experience with Scan but I strongly recommend Overclockers UK.

Thanks for that input, JaF. Of course, I'm now more confused than ever, buy, hey, you get that.

Anyway... I suppose I shall have to make a decision within the next few days, because it is really quite inconvenient not having a computer of my own.

Any other comments, everyone?
