​I have decided it's time to upgrade my case as this one is getting a bit old!
I've gone with a Corsair iCUE 5000X, I'm just waiting for a new PSU to get here to replace the old Corsair AX860i.
I was going to go for a Seasonic TX-850 Prime, but it only has a single rail and no option to set it up to be multi rail, so I'm going to get a Corsair HX850.
The PSU should be here tomorrow, so I'll post some pictures soon!
