Gaming desktop for under 400? (inc. monitor) please help!

[Davey LC]

I don't currently have a pc so I can't upgrade, I have 400 pounds to spend on a gaming pc that would play games such as starcraft 2, c&c 4 and other rts games, I'm willing to build from scratch as i understand it will be cheaper, any help is massively awsome as the range of components is ements and confusing but my knowledge of what needs to be done is not too bad. A few different choices would be good to compare them, thank you loads to any1 who can help me do this I really need it lol.

To be honest I cant see you getting a half decent gaming PC (even without a monitor) for £400.

Would you say it would play starcraft 2? Would you change anything?

Gaming desktop build, help greatly needed!!

I'm also looking to build from scratch to save money. The following specs are what I have come up with so far, so if u think I should change anything or you have a different idea then your feedback is massively welcome, could really do with some advise! Thanks.
