In my experience:
10/32 - sound and video racks
12/24 or metric - data racks and server cabinets
The only place I've ever seen 12-24 are the screws that HP ships with their switches. I don't have a single rack anywhere that can take them.
Even my racks that have no threaded holes, came with cage nuts that take a 10-32 screw. Maybe they do things different in Canada.
I like using the 10-32 screws that Dell supplies with their servers. They have a large flat head and the threads are of good quality.--
