Hello.
I'm planning on building my own pc soon for gaming and some Uni work.
I've done some research on the interwebz and this seems to be a pretty good spec considering what I’ll be using it for.
I am still unsure about a few things though and would like to ask for your help:
First up, the case. I really can't decide between an Antec 300/902 or a CM 690/scout. I'm looking for good cable management/cooling performance. I've heard good things about all of these cases, and they are all below £100, so it's between these guys. (Could be tempted by the HAF though...)
Second, the motherboard. Would this be a good choice for an AM3 board and to compliment the Phenom II X3? Or is there a better choice for over clocking etc?
Also, the RAM. Should I just get some DDR2 RAM instead? I'm assuming that AM3 boards support them?
How about the PSU? Should I downgrade to the 520w for a modular one? Or will cable management be simple enough with the 650w? 520w would be enough for my needs anyways, right?
And lastly; I have until the end of the summer to build this pc (sometime in September) would you recommend waiting till then, or buying and building now?
I'm trying not to go too much over £850 to make myself feel better about not getting an i7 setup.

Sorry for all the questions, any advice is appreciated.
