You can take this opportunity to learn a new skill set. The metal casings need not be CNC, though many probably are. Many electronics hobbyist use to make their own chassis, or at least punch the holes in pre-made rectangular boxes. And they did it quite cleanly. Aluminum is a relatively soft metal. With an electric hand drill, maybe a jig saw (metal bits), a sturdy vise, and a set of files, you can do some pretty good work, given a little practice.
The common tool used to punch a chassis is a "chassis Punch" sometimes called a "Greeenlee" punch after the major manufacturer.
Two parts joined by a big bolt. As you tighten the bolt the Cutter is drawn into the Die and makes a clean cut. They even exist in versions to make rectangular holes.
