I live in the UK and I'm looking to buy a desktop computer, since my current computer (which I bought in 2004) is falling apart. My monitor and speakers are in a reasonable condition so I don't need to replace them. My criteria are: - Must be Â£500 or less - Good quality components, esp. a good cooling system - I don't have A/C in my study and its gets dusty at times. - Reasonable customer service - Up to date, since I enjoy playing computer games. Any recommendations (other than self-build and importing from the US) would be very welcome.
