haven't built a computer for a couple of years now and was wondering if anyone had any ideas about this built and whether it could be made any better for the same sort of price i will be eventually overclocking this build to around 4ghz

i will be grateful for any of your thoughts or ideas

well i did quite a bit of looking into the h50 and eventually decided to choose the megahalems over the h50 due to the fact there isnt much difference between them and the known reliability of the h50 thanks anyway tho
