Looking at how long those wires are, definitely custom cabling would be in order. I'm certain I would take pride in doing it myself, but I'm kind of dreading the tools and time investment and trial-and-error that might come along with it... I may end up just using some string to measure stuff and ordering cables.
I think a relocation of the power switch and USB headers would allow me to keep them, they're far from "square" with the left side going with the perspective of the picture you posted. I think if I took them out, pushed the HDPLEX over pretty much flush with the corner of the case, I could put the board with the switch/USB headers towards the center of the case. I might just be being optimistic here, though.
Regarding the card's power draw, the site itself actually says 225W, for whatever reason the "specifications" section only says 150W, but further up in the 'marketing' info on the card is where it lists 225W.

Anyways, I'm still scratching my head and hoping there's a way to fit both a 300W HDPLEX and the AC-DC brick in there... I won't hold my breath, though.
