Damn, that’s a really good point.

In this specific situation, looking up the specs for hard drive screw mounts means you can skip a lot of the manual measurements.

You can certainly still measure to double check specific placements, but the spaces between the holes, and the height above the deck should be standard.

Heck, just knowing the measurements of the hole spacing and the internal dimensions of the hard drive space can be used to double check all your other measurements and have more points of reference.
