I was trying to figure out a good way to mount a SSD in a used Lenovo system I picked up the other day and noticed that the steel strapping (fixing bands in the UK) I had laying around perfectly fit the front to back alignment of the bottom holes. Looks like crap, but if nobody ever sees it, who cares? I'm not sure if the holes are a standard distance apart that's common across manufactures and countries, but I figured I'd post it here incase it helps someone out.
