Closed $120 300W HD-Plex (w/ cables)

I'm selling my 300W HD-Plex with the cables that come with it. The DC power adapter has been cut out to work with large graphic cards in an S4 mini. Everything works great. I am switching to a more powerful power solution and don't need this unit any longer.

Stock unit, used with modded adapter inlet = +35 USD over retail? Is the 300W a collector's item now?
