I was looking at building the uk recommended £900 build. I chucked on a CPU cooler that someone recommended and a nice looking case. Unfortunately the 1070 is about 60 quid more than it is listed as, because of import tax. I'm at a bit of a loss as to if I should look at doing a different setup, or just put up with the extra cost.

I'm trying to make the PC quite quiet, otherwise I'm likely to get it in the ear at night time. Not overly fussed about lighting or anything of that nature, as long as the case is easy to clean as we have 3 cats.

Any recommendations would be appreciated, I know the current build is a wee bit out of date, and there's been a lot of releases over the last few weeks.

Many thanks!
