My new PC build is finally complete. After two weeks, four RMAs and endless head scratching, the final specs are as such:
Intel Core i7 8700K
Asus ROG STRIX Z370-I Gaming Mini ITX
Gigabyte GeForce GTX 1070 ITX Edition 8192MB
Corsair Vengeance LPX 16GB DDR4
Fractal Design Celsius S24 AIO cooler
Super Flower Leadex GOLD 550W PSU
Samsung 960 EVO Polaris 500GB M.2 SSD
4x WD 2TB HDD
Fractal Node 804 case
Only had a bit of time to mess around downloading drivers and watnot this afternoon before I had to go to work, but finally all my work (and money) has paid off.
