Ah okay.

I like the twistlocks so much, would never let em go!

I put 30A twist locks on them, they were cut from the prior owner on mine 
(the plugs were hacked off but there is plenty of power cable.)

Man up! Mine is J932 so the CPU cabinet is about 2.5' - 3' deeper than the 
disk cabinet. There are these silver square box things with screw holes on 
opposing sides. Screw one side of them to one side, and swing the cabinets 
together. The floor needs to be fairly level. I usually find it's easier 
to push the disk rack around so I mate the disk rack to the CPU rack. I 
assume the CPU Rack on a J916 is quite a bit lighter (but not light.) 
There are screw holes for that hook together block on both sides. Maybe I 
just finger tighten the one on the CPU rack because it's hard to access - 
can't quite remember.
