We don't have any solid evidence that Core i7's are that much better for gaming. The performance difference may be worth 700 Kr, or it may not be worth anything. Unless you mean to overclock, the 4690 (non-K) for 100 Kr less might be the better deal.
I've been thinking, can I use a Mini tower and not be afraid of overheating? I will never overclock, it is not something I do.
Just thought it be nice with something that didn't take so much space.

PS: This is what I had in mind:
Corsair Carbide Air 240 Cube Case White
Cooler Master V650S, 650W PSU
ASUS Z97I-PLUS, Socket-1150
Intel Core i5-4690, 3.5GHz
Crucial DDR3 BallistiX Sport 16GB KIT
Seagate Barrucuda SATA 6Gb/s, 16MB Cache, 7200RPM
MSI GeForce GTX 970 4GB OC (Witcher 3 digital voucher)
Total cost: 10 955 kroner
But..
How much better is this than what I have now:
Intel Core i7-4700HQ 2.4GHz
8GB RAM
NVIDIA GeForce GTX 880M 4GB
