I am currently rebuilding my closet and all of my DC equipment is getting
powered by a single PC power supply (no more wall warts).   It's trivial to
splice the plug from your bad power supply onto a molex splitter (use red
and black for 5v, yellow and black for 12v).  I have a dedicated supply for
my equipment (4 HD PVRs at 5v and 4 Cisco STBs at 12v), but if you just
wanted to test it, you could easily use your backend's power supply to
power your HDHR.

Just cut the cord from your bad power brick, and splice it into the red and
black wires on a molex splitter or molex>sata adapter:

wires, but you get the idea)

Unless your overloading your power supply, pulling 2A off the 5v rail
shouldn't hurt anything (after all, your usb ports pull from the same rail,
and I wager you can safely charge a phone or two on your system)
