OK thanks , I Know ideally I should have gone for something like corsair or seasonic but I just bought the FSP hexa 500W as I felt for £20 refurbished it was pretty much the best value for money PSU, also I was on a budget & it wasn't really refurbished as it was a pull from a machine which a customer had returned under ?? week return period & the PSU was almost new ( they just had to sell all the parts in the machine & replace it with new because they had techinally bieng used for a few weeks), for my two personal rigs I am using an XFX 550W core Edition (intel core 2 quad q8300 Rig) & XFX 750W Core edition (intel core i7 960 Rig): See my Configuration(s) link
also the case are you reffering to the Atrix 9001?, if so that case is Just an older case I have, the case I used for the pentium G620 Build is a: Ezcool NA-705B
that Atrix 9001 has nothing to do with the PC Build BTW, its just a recent mod I did on an older case I have.
