It's a
Cherry MX 8100 G80-8113LRBUS with some
colored keys (woo!):

Yes, it's an ISO layout—but as colored keys aren't often seen on boards like these, and some of you go wacky over that sort of thing, I thought you might like to know.
Some of you may even consider buying it just to remove and use those 5 caps. (Since I learned people were willing to pay hundreds of bucks for
one keycap, nothing surprises me.) It has some nice vintage-y Cherry switches too, of course (probably Clears or Blacks).
BTW, don't forget your relaxation exercises. :?)
