What about making a CAD file and have the whole stack of crap CNC'ed

?

The only tool doing all!
Table-saw, hand-saw and router is the most versatile/precise set when DIY at home. For tiny things a fret-saw can be a marvelous piece of equipment too (forget that kids-hobby-club-christmastree-sawing nightmares)

For the bulk . It is not very practical to buy yourself, but boy find yourself a woodworking shop where they have it. Its worth one Million donkey kong points! Did I say 1/5th mm and 1/10th degree angular precision! Try that with your hand-gear.

For the sharp angles, those last cm's a table-saw cannot reach. It is better than a jigsaw for these last bits as it is wanker-arm-operated, so no going too far, the width of the cut is more simalar to the table saw blade and the cut is very straight.

For weird shape joystick/trackball holes.

For large round holes (speakers/trackball), curves and T-molding.
