I would suggest very strongly that you twist those wires together in pairs.
........keep them isolated from the everything that is a potential source of back EMF or noise(as in that wire harness for the Y axis draping over the motor...bad idea). You dont want anything that would interupt or add to the pulses coming from the drives to the steppers.
The signal pulses will cross talk and you will have erratic stepper movement resulting in extra/lost steps and severe positional inaccuracy if you dont(and possibly a good reason to be visiting geckodrive.com again to purchase some more drives) twist those wires atleast.

A better idea is to use shielded cabling for the wiring outside of the PS box(cant tell if you already do or not from the pics)

Those are some long runs for the stepper wiring...do you have a suitable capacitor on each axis, as per the gecko white papers?

Thats a pretty decent job.

Im curious about one thing in particular.....how do you intend on using the rack and pinion drive in manual with the leadscrew stepper asssembly attached to the head on the left side?

Its early maybe I missed something in the pics......

I can't wait to see, I'm also all most done with my conversion as well.

I just take out the two screws holding the threaded leadscrew nut and that will let the Z move by hand.
