I really do think that is a bang-up job man, truly the bee's knees!
Please do not take this the wrong way, but just one little thing I would have done differently is that I'd have soldered the wires direct to the PCB, rather than busting up the old power connector.
Too many good points to note about this conversion, like the power button...the silver matches the standard rear ports...really looks "in place"!
Again, very, very cool!
