Generic beige-box PC clones like the ones pictured here often had an indent for the manufacturer's badge to be stuck on. Were these all a standard size, and if so, what were the dimensions?

One inch square, I think (at least, the insets on my old, beige, midi-tower cases are).
- 2Thanks! Looks like they're currently made as 25 × 25 mm with a 2 mm corner radius. I was blanking on what these were called, and it seems the term is Case Badgescruss– scruss2019-06-28 23:03:28 +00:00Commented Jun 28, 2019 at 23:03
Measurements of my IBM Model 5150 indicate the badge itself is 1 in. square, equivalent to 25 mm. But there is an additional approximately 1/32 in. added for the indent area, thus allowing the badge to completely reside within the indent.
For "clones", I suppose the ones deemed "100% PC Compatible" would need to match this size, precisely. 
As can be seen on this picture of a Selectric typewriter the badge there is very similar.
My guess would be that it was as simple as "We need a place for the IBM badge".
