Mel,
Your determination of the required shelf length sounds quite reasonable.
If you are working with plywood, a normal maximum length for a bookcase
shelf of 3/4 plywood is 32 inches without interim supports.
If the shelf is going to be longer than that, or you will have
substantial weight on the shelf, glue 1 1/4 or 1 1/2 inch high edging
strips of 3/4 inch thick solid wood to the front and back to conceal the
plywood edges.
To keep the shelf assembly from racking, rabbet the back of the assembly
and fasten in a 1/4 inch plywood back - then cut large slots (at least 3
inches wide leaving 2 1/2 inches of material at the ends and under the
top) in that back panel to provide adequate ventilation and space to
pass cables through.
I have had considerable woodworking experience both as a hobby with 10
years running a small custom woodworking shop and doing specialty
designs for customers. Make it look like furniture - go to a shop that
deals in hardwoods and buy quality materials. If you buy at a DIY
store, check the materials carefully to be certain sheet goods are flat
and the solid materials are not warped.

Depending on the desk top, the routing of the cables can be a mess. I put a
false back and dressed the cable through slots and the mess was behind the
panel. A thought.

I've really enjoyed the conversation about shack and desktop setups, as I'm
about to get into the garage, get behind the saw, and build a desktop
equipment shelf.
I've been talked out of building vertical supports, thanks to this
list.
