hey i was just woundering if someone could help or view the pc parts that i shall be getting and to see if i have mucked anything up. this will be my first time building a pc so i hardly know anything :S. here is what i have so far.
As for your case as your motherboard is an ATX size you will need to get a big enough case to accommodate it, you do not state what your budget is for your case.
I do not know what your overall budget is but if you are looking for gaming performance then the Intel i5 2500K is a better CPU tie that in with a Z68 Gen3 motherboard, which comes with PCI-3 for the next generation of graphics cards,useful when you come to upgrade, These two are a better combination for gaming. You might want to look around for a GTX 580 as prices have come down since Nvidia brought out its latest GPU, the 680.
But it really depend on your overall budget of course. There is nothing really wrong with your choice but you may be able to do better.
This spec is from Scan a little more than your £700 but I think better overall quality. Scan The case in p[articular as Silverstone are known for their case builds.
Next one is from Aria, I have never heard of that brand of graphics card and I have been building for a while now but it is a little cheaper. Aria.
As you can see they both include the i5 2500K and a Z68 motherboard. I have not included a cooler as the stock ones that come with the CPU are pretty fair these days but you can always add one later if you wish.
