At this point you should start using pcpartpicker.
https://uk.pcpartpicker.com/parts/partlist/
It will help you identify all the parts, show compatibilities/incompatibilities, calculate approx power supply size and show you part availability and pricing. It also helps you do a lot of what-if calculations quickly and simply.
I believe you said you were moving to the UK. If you have the option, consider buying a Dell XPS with the 6700K and 256GB SSD.
My most recent build uses the 6700K, liquid cooling, 32GB mem, GTX960 with 4GB, and Samsung EVO SSDs - for OS, Photo working sets and cache, catalogs, etc. I use WD Blacks for photo storage and 4TB WDs for external backup. The system is mildly overclocked at 4.6 and you can do this easily just using something like the ASUS Z170 motherboard and using its OC utility. It's a no brainer. It cranks up the settings and tests automatically.
My cousin just bought a Dell XPS with the 6700K, air cooled, 32GB, 256GB SSD, GTX960. We added an extra internal spinner for storage. He's running it not overclocked, it's very quiet, it cost less than my build and in normal day to day processing - PS, LR and a ton of plugins, you can't really see much of a difference, if at all. I set it up for him and it was a no effort proposition - works like a charm with Win 10. Just like this one:

It replaces an older Dell XPS he's been running 24/7 since 2010.
So, if you build, use pcpartpicker. But also consider buying a Dell, most of the goodness at a lower price point and a lot less drama.
