Could someone help me with a £300 PC build?

[Adameh]

I'd probably be the last person who you would expect asking for help on a PC build but I need help as I'm clueless. I'm not really looking to play high end games either. I just need a PC (no monitor, OS, keyboard and mouse) for around £300 that can play some games. I can always upgrade it later :P. I also need help making sure everything is compatible. I'm counting on your help :P
