Actually, from where I'm from (Europe), the Gigabyte GA-Z87X-OC Force is cheaper than the GA-Z97X-Gaming G1 these days 
The difference between Z97 and Z87 doesn't seem to have influence for the build:

As for PSU I'll look into either LEPA G1600-MA[-EU] or some other LEPA PSU: http://www.lepatek.com/eng/product_content/1/1/64/ - I haven't seen such powerfull PSUs from more "common" hardware brands (like Corsair).
I can double the memory without much cost at the moment.
Thank you Szulk and Flomac - I'll get back soon with an updated list.
