Changed Parts from OP:
-Sexy Factor Changes-
Motherboard - should go well with the Kraken cooler aesthetically
Case - Sexy af, Some RGB lights, 8 pin fan hub inside, there's also a few other color combos on the NZXT website
GPU - it's the same but it may not go well aesthetically with this case(I didn't change it since it is at such a nice price)
-Practical Changes-
HDD and SSD - Same models larger capacity (so you on't have to worry about it for a long time)
Memory - Little Higher Speed Ram
If the Sexy factor changes aren't to your liking I would still recommend going with the higher capacity drives.
