There should be
some plastic catches (or more likely the remains of same) on the PSU.
I've found that most half-inch tape seals have latches which are
quite amenable to being used as replacements for the original plastic
catches :-).
BTW, one of the few pieces of poor design in this
machine is that you
have to take the left side rackmount rail off the box before you can get
the PSU out. This means you have to take the entire (heavy) machine out
the rack before you can remove the PSU.
If you use short 10-32x1/4" screws on the left rail, it's a lot easier to
take the PSU out. (I thought everyone shortened these screws!)
With the original screws (3/4"), it is possible to get the PSU in and out
with the rail attached, but it is quite difficult and requires that the
PSU be inserted at a rather awkward angle.
