https://www.modushop.biz/ - among other things, reasonably nice rack-mountable cases
*** EDIT *** I didn't notice Modushop were in the list already - but only in the "custom / engraving" section, for some reason(?) *** END OF EDIT ***
http://www.altinkaya.eu/17-19-rack-enclosures - in my searches for an even cheaper "blank" 2U 19" rack case, i came across this Turkish company. Dirt cheap - and i mean DIRT CHEAP small-size die-cast enclosures as well (think guitar pedals and whatnot)
That being said, how feasible would it be to perhaps also classify the list in the first post, by geographical location (as well)? Or at least indicate where each are based?
I think everyone will agree, even if you find some good-looking affordable items, often the shipping and/or customs can really be quite the buzz-kill, to say the least
