No, you certainly don't want to remove any of the input bulk capacitors.
Look at the picture. Above the smaller part of the PCI-E slot connector you'll see two large "000" marked SMD resistors (R450 & R451). Measure if A) both of the resistors are shorted together, B) if they are shorted with the drains of phase 4 - 6 high-side fets (Q510, Q507, Q515). The phase 4-6 high-side fets are the lower three fets in the region shaded in green, and the drains is the part marked with a blue line. If both A) and B) are true, you can try to remove R450 & R451 resistors from the board.
After that you need to measure that upper pad of the resistors you just removed is no longer connected to the 12V pins in the PCI-E connector (shaded in orange). If there is no connection, then you can solder 16-18AWG wire to the upper pads of resistors R450 & R451 and feed 12V directly from the PSU on these. The empty DVI connector PCB mounting holes should provide you a nice ground.Edited by The Stilt - 7/7/16 at 3:36am
