When working with aluminum I always use masking tape, digital calipers, and a 0.3mm mechanical pencil for the layout work. I took a tiny little slot screwdriver and grinded the tip to a sharp point and I use it to precisely mark the center of where I want to drill. Once I have the spot marked with a little indention I use an automatic center punch to turn it into a little crater. That little crater keeps a 1/16" drill bit from wondering and actually gives pretty dam good accuracy. Then of course I just work my way up drill sizes to get the size I need. The screws are stainless steel 1/4"-20 x 1" button head socket cap screws from Home Depot. The threaded inserts are from HD too. Here's one being screwed into a piece of oak:

Cast concrete! got to be the best enclosure no resonance.

Make a plywood form. position dowels (bits of pencil) for the holes.

Fill with concrete, weave it on the washing machine (running) to shake out any bubbles.

Perfect enclosure. You could cast isolation spikes too.
