i'll use just the cpu on WC now. Full cover vga blocks are inexistent here in Brazil, and importing will cost more than the whole project.
The orientation will remain stock, as I've done 3 inverted cases recently, and I'm trough with it for now.
The exterior rad is to keep the ATX-frienldy layout. If a mainboard change is at hand, I could choose any. i love Matx, but flexibility is always welcome.
The rad will not remain outside for now, because my current vga is single-slot, and there is no other pci used. Internal rad looks cleaner.
