Another compatiblity question

[almecr]

Hi Tom's Hardware,
A friend of mine wants a computer for £450. I looked around for a few hours and found what i would consider a mid-high end gaming PC. Could youll tell me what you'll consider it. I'm also not sure the power supply is enough, i'm only getting it because i'm getting the case and PSU in a bundle and it's £7 cheaper then buying them separate. Would this be able to run BF3 at mid ? By the way we're both 15, but my dad paid for my PC(£650 w/o monitor) but he is just using some birthday money and other money he has. The parts i found go a little over budget and could you'll please tell me if they are compatible. Can i use an OEM Operating System for a new build, i think i did for my PC. Last question, would i need any more cooling seeing as it is a 6 core CPU and a factory overclocked GPU. I am getting one 120mm back exhaust fan, is that and the front 120mm fan enough ?Thanks people.

Thank you again Tom's hardware and sorry for the very long question

At that budget,
You'd be better off with an i3 2120 for cheaper,it's more capable. You can get that with a h77 board in a bundle perhaps with ram even.
The psu isn't the best,get the case without it. Then look for xfx,antec,be quiet,seasonic. 450w 80+ should do fine.
A front intake and rear exhaust will suffice.
