I don't think I have have *ever* seen a white-box clone with FCC classification stickers certifying the assembled unit. Not ever, ever, ever. In one of your pictures the power supply *does* appear to have an FCC sticker on it, however. If the case and power supply were sold as a unit then only the power supply needs the sticker. (And to cut off the possible objection, that still applies if that's not the original supply, of course.)
That case that I really wish I still had to take a picture of looked *exactly* like that from the front, to the point that I would bet money it was stamped from the same tooling. Ever think that maybe the company that designed it might have perforated the front panel like that because it would let them move around the locations of things like the power button and LEDs and sell a line of seemingly distinct cases that just had a different plastic bezel? IE, if Joe Blow Cloner Incorporated agrees to order (some many hundreds/thousands) of the things it qualifies them to get their choice of bezel with a milled logo and the switches wherever they want? That actually argues strongly *against* it being some sort of prototype for a specific form factor, a prototype wouldn't have all these neat universal features that let the OEM's customers pick and choose and mix and match bits and pieces to get exactly what they need.
Your comparison is meaningless, it's a sample of *one*. I've owned generic tower cases that you could probably climb up on top of and jump on without hurting, while I've had others that you could literally crumple up in your hands. (I'm using the word "literally" correctly according to the dictionary meaning in that sentence, no exaggeration.) The cost difference between the two when new would be about $60.
I could pick up a diamond and a piece of pencil lead and froth for hours how they're not ultimately the same thing because one is so much sparklier than the other but from a chemistry standpoint I'd still be wrong.
Anyway, again, if it makes you feel good believe whatever you want. Clearly you're not to be convinced here.
