Need a case suggestion

[rasesh]

Hey guys if this is my build:

CPU: i7 6700k
Memory: 16gb ddr4
Mobo: Asus ROG Maximus VIII Impact (Mini-Itx)
SSD: 250gb samsung
HDD: WD 4TB 7200rpm
CPU Cooler: Depending on my question im about to ask

Question: If i'm thinking of strictly performance but wasn't going for a GPU as the onboard is good enough for me and i wanted the smallest ITX case possible WITH a good sized window like the evga hadron air or the Raijintek Metis case what case would you build this system in, taking into consideration aesthetics is important hence me mentioning the good size window. I MIGHT get a small GPU although it's not that important to me.

Any suggestions?
Thanks!
