Hey peter....!
Funny you should reply, I was on your site last night to see if you had
instructions/plans for how you built your frankencase.

So here's the deal. I built SIX custom cabinets, which stack together
to make a two franken-towers. Top four cabinets hold a G6 or more each
with its own PSU, just like they come new.

Now the bottom two cabinets are a bit different as they are very shallow
because of the angle. They required that I make some custom rack ears and
mounting rails. I took the bus boards from two G6 cases ( these cases are
no longer being used, right now anyway) and mounted them in the new
cabinets. I took the PSUs from the two G6s and mounted them also. One of
the G6's was bought used and did not have the MAINS INLET, also the cabinet
is too shallow to mount the G6 back plate which normally holds the switch.
Oh, also both cabinets will eventually have two rows of modules each and I
thought that might be too much for one PSU2.

SO............. I thought it would be best to steal the mains power from
one G6's mains switch and run the wires to the other PSU. Or I should get
another mains switch with fuse, I just want to get things running asap. All
the wiring is done, good mains cable stuff. Just waiting for an answer so I
don't start a fire or something.

Thanks

nick
