Photo in the current state:
Only frame left from moment i bought it.
It’s mongoose switchback expert. Photos made by seller:
As we can see it had mechanical brakes and SR Santour fork and other shitty stuff 
Current fork is pretty old too (but I bought it new) — it’s rockshox 30 silver with 100mm travel steel coil:
As experiment i was trying to replace coil with air cartridge from newer fork, no success
*almost success, but I was unable to do some precision work manually (like thread cutting inside tube with thin pipe wall), so I forgot about this idea
Handlebar was nukeproof warhead for years, but i’ve replaced it with chinese carbon one named «ec90». Will see how long it lasts. I already did some small jumps and bunnyhops with it and i’m still alive
Barebore — ZTTO:
Brakes old Shimano SLX with the new front caliper, because old one was broken.
Transmission is 1×12 speed shimano slx with 12 speed CNC cassette from aliexpress for Shimano HG hubs. It’s pretty lightweight (right one):
Rims are tubeless nukeproof generator am.
Crankset is old shimano xt painted in black and chainring is «Deckas» 38T 7075 aluminium from aliexpress.
Hubs are ZTTO DR190 with ratchet, i heard that 54t ratchet is a weak link here, so i already have the replacement with 18 teeth ratchet:
Pedals — last 5 years meetlocks aluminium pedals with 3 ball bearings from aliexpress.
Almost first photos of it:
With the stupid xenon light And non-stock Avid BB7 front brake:
Here with the new handlebar:
