Need any adjustments before ordering soon

SSDs have really come down in price since I bought one. Looks like a decent build. Not that there's anything wrong with your parts, but for my personal tastes I would get a seasonic PSU and get western digital over seagate.
 
The only part I'd recommend to change would be PSU, other than that it's a decent build.

Best quality PSU's would be Corsair RMx, TXm, HX, AX series. EVGA SuperNova G2 and G3, SeaSonic Focus Plus Gold, Prime Ultra, Prime Platinum series. be quiet! Straight Power 10 and Straight Power 11. Super Flower Leadex II.
 
For what it's worth, the first review Toms did on the seasonic prime platinum said they were blown away by it. That's what I put in my system last year when the store was out of the Gold one (on sale) I wanted. Cost quite a bit more though but I'm happy with it.
