Although the originality of the configuration is not original anymore
and the h744 is beyond repair and a replacement cannot be found,
you may consider to use a BA11-K box instead and transfer the
backplanes and console sub-frame to this type of box.
(This is the box which one has the power supply at the back and
can support up to 4 power bricks.

Ugh. It was a fairly disappointing day on the
PDP-11/35 restoration front.
I've updated my restoration journal (
http://www.loomcom.com/projects/pdp11-35/index.html ), but in summary, my
H750 power supply is one big gross mess.
Take a look at the condition it was in:

All that pink stuff is fiberglass insulation. Mice got into the power
supply, and made it a nest and toilet. Everything is soiled, and lots of
exposed metal is corroded.
I'm feeling kind of low about this. I do believe this is restorable, but
the amount of time it's going to take is bumming me out. I'll have to
disassemble everything, right down to the last screw, and clean anything
that's cleanable, strip rust off of anything strippable, and test all the
parts individually. The fan will probably need to be replaced.
Plus, it's just yucky, y'know?
At least I've cleaned out the mouse nests. That's a start, I guess.
