Hello Fractal Design,
Regarding your new Core 500 case ,
I hope you did not start mass production ...
here is the minor thing you missed ,
the case width is 250 mm and looking at the rear of the case I can see that you wasted 20mm to the left where the power plug is installed.
here is the catch , Cards like Titan Z are THREE SLOTS CARDS.
so this 20 mm to the left should have been used to the RIGHT making it a 3 slots case instead of 2 slots case.
MANY cards are 3 slots . and MANY people will use this case with DUAL GPU 3 slots cards coming in the near future for the lack of slots in itx form factor!
it is a WONDERFUL CASE !!! but why on earth waste 20 mm to the left ? use those 20 mm to the RIGHT making it a 3 slots case .
as for the power plug , it can be placed over the third slot there is enough space above the cards because you allowed 140 rear fan in the case.
I hope you did not go for mass production
keep it 250 width but use the that for 3 slots and put the power plug over the third slot place !
here is my mod to your case :
