I bought both my HRF's new, and while they show some obvious signs of use after about six years, it's mostly in the places where you'd know the cameras have had some serious film mileage (worn paint–anodizing?–around the shutter-release collar/mode switch). Except for a few nicks here and there, the paint finish is remarkably hardy, and since it's a mostly-flat epoxy finish, it's pleasantly warm to the touch...not a small deal to me at this time of the year. Never used a case with either one; that's what my Domke F-803 is for.
I'd say, if you want a case that doesn't get in the way, a Luigi half-case seems to be a good choice. But don't sweat a few small nicks here and there. A "mint" looking camera is one that likely hasn't seen much of interest, and where's the fun in that?
Enjoy that Hexar!
