I didn't originate this idea, but if you're curious about other options... I found success using an IKEA Helmer for my home lab.

IKEA CORRAS FTW. https://www.neilvandyke.org/machine-learning/super-in-ikea-c...
I have a couple of these, they are made of a light gauge sheet metal; the inner dimension is ~9.75", wider than the 10" standard hole spacing; and I don't think they would be very structurally sound if you were to remove the back panel. Doesn't seem very well suited to me.
can you share a pic?
Thanks for sharing. I’m running a lack rack for 15 years, would have been fitting
https://github.com/bwann/homelab documents this sort of setup. Looks great!
