very simple, contains only the essential bits dimensions of which play
important role in the case design due to size restrictions.
there are two std parts: regular with sketches with sketches to
construct the body, and a simple refined version for the provcase
assembly.
the regular variant also has a master sketch to aid in defining
constraints in the provcase design.
all are parameterized via the asmsheet which now includes
a calculation for an exploded view.
while there, added the missing display standoffs.
what's still missing is:
- SSD board
- heatsink top/bottom spacers
- outer case walls and mount holes
