I was thinking of going with
Rosewill THOR V2-White Edition, THOR V2-W Gaming ATX Full Tower Computer Case, support up to E-ATX / XL-ATX
with a
GIGABYTE GA-990FXA-UD7 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 Extended ATX AMD Motherboard
and a
Rosewill Xtreme Series RX850-S-B 850W Continuous @40°C ,80 PLUS Certified, ATX12V v2.2 & EPS12V v2.91, SLI Ready CrossFire Ready, Active PFC "Compatible with Core i7, i5" Power Supply
Does that look compatible?
