Well you could use a router or even a CNC mill.
A x/y table or maybe even just a guide pattern would suffice.
You could also use a punch to make the holes.
Personally i use nibbling pliers like these:

(people kindly sent them to me from the US).
I also have a different version, more suited for longer cuts:

There are even motorised versions of nibbling tools, depending on how many
holes and what size you are going to make...
For cutting the outside contour, i use a sheetmetal shear (lever actuated
bench shear).

People use all sorts of equipment for that purpose, jig saws, circular saws,
tile saws, paper shears, bench shears, tin snips, etc...
