This is an overall better build , with a very high quality PSU ( which is semi modular BTW ) and without breaking the bank :)

I agree but I only had £350 overall to spend and I got most on my stuff on sale a while back like to motherboard for £40 and i'm also reusing older parts such as the HDD and RAM. Thanks for the help though :)
 


Mmm... how hard is cable management with a non-modular psu?
