What chipset is that mobo? G43 doesn't tell me enough. There's no reason to get a K-series Intel processor unless you get a Z chipset board (z87/z97) so you can actually overclock it. Without overclocking, you're just paying extra for a feature you're not using. Are you using the stock cooler (not recommended for overclocking) or did you also buy an aftermarket cooler for the CPU? Also, that build is within this year right? If prices are so bad in the UK, what prevents you from buying from US retailers and having them shipped to you? Is there some kind of tax you have to pay for that?
The reason I ask is because that's almost identical to a build I would love to do if I had the money. I love all those parts, except I probably would have gone with a different case just because of my personal preference.
