jeff pal, nice score, secretly wished I had seen that classified myself.
Anyway, I am in the same boat as you, out of the market for a long while, not as familiar as to the offerings these days.
I was looking at some builds sold on our classifieds section as reference and to get some ideas...

oots YBB frame, titanium, 2cm travel, 18" size.
Magura Durin Marathon 120 fork, with adjustable travel from 80mm, 100mm, 120mm. The frame was built for a 100mm fork, but I've been running it at full boing with no issues. If you care to ride it closer to stock, you can lock the fork out at 100mm of travel.
Mix of generations of Shimano XTR shifty bits -- earlier cranks and shifters, more recent derailleurs. Everything works well together.
Mavic Crossmax SL UST wheelset with fresh Schwalbe UST tires -- Nobby Nic front, Rocket Ron rear. Only a few rides on the tires.
Formula K24 Oro discs with Twenty6 two finger lever. GREAT brakes.
FSA bars and stem, American Classic seatpost, Chris King headset (I will be swapping the pictured pink headset for silver.)
