TBH for £700 that build is about as good as it gets and is excellent value for money. You might be able to shave off £20 - £30 by getting a cheaper mobo but frankly - for the money - I'd stick with the one you have chosen. It'll be very capable for the next 3 - 4 years.
Hmmm, I think I'd like the SSD from the get go purely for the O/S. I reckon I'm gonna play the Black Friday game, let that be the catalyst. Any sites with good past Black Friday deals to keep an eye on?
I also looked at these because I was worried about installing the CPU and cooler but honestly it's very simple and you'll be wasting money.
The processer just sits in place as long as you put it the correct way round and most cpu coolers come with thermal paste applied so it's just a case of fitting it to the mobo.
