Re: I just recently picked up an R7 and see several of the newer cases gutted for sale and I was curious the reasons why these proprietary cases are gutted for sale is probably because these cases are very difficult to reuse for newer motherboard.  R5-12 case power switch is embedded in proprietary led multi pin controller.  The Pwr sw pinout varies between models.  Note R9-12 uses gen 3 chassis that has completely different led design from gen 2 chassis of R5-8.  Even if someone manages to power on R7 board inside a R9-12 case, or vice versa power on R9-12 board inside a R7 case, led is most likely going to be unlit. user report of Pwr sw pinout of white 12 pin motherboard header (from left): not verified. R5 ? R6 pin 3 and 4. R7 pins 3 and 4 R8 pins 4 and 5 R9 pin 3 and 4. R10  pins 4 and 5 R11 pin 4 and 8. R12 ? PS R5-7 cases rear I/O shield are not removable.  
I see several posts about moving internals to custom/aftermarket cases. Has anyone attempted moving older Aurora to new Aurora cases. I know it’s a funny concept as everyone wants to run away from the flaws in case design.  I just recently picked up an Aurora R7 and see several of the newer cases gutted for sale and I was curious?Give an older unit a fresh look.
Aurora R7, swap to new Aurora R9-12 case?
