I have a HP 8300 SFF desktop with i7 3770, 16gb ram, 2TB HDD, 256 SDD & GT 1030. Recently i came across some videos which show use of PCI-E riser cables. So i was wondering that can i use a GT 1060 or 1070 with PCI-E riser cables and an external PSU connected to the GFX card? Card will be mounted outside the desktop via help of riser cable.. Expert opinion & help required. Thank you
