Wanted- MTB beater gear/offcasts

So I'm building up a beater MTB. Currently have and XC frame and forks. Need everything else, fairly cheaply. If you're getting rid of anything that could help, or have something sitting around, it would be appreciated. Can and will pay, but I do need to keep this as a cheap build- it's going to become commuter #2, so nothing that will cause tears if it's stolen. On the flip side, nothing that's ruined either, as it would be nice to get to work on time (occasionally).

I've got a box of old bits in the garage I mostly keep for spares for the kids in the street that pester me during the summer hols (though broken frames are well past my skills..lol)
I've triple front & rear derailleurs that are complete though I can scrounge some bits off others to get them functional if not. bottom or top pull for the FD? (I've got 28.6 and poss a 31.8 fitting) I've also got a 48/38/28 c/set with well stuck pedals or indeed a 42/32/22 with fairly shortish cranks..again pedals firmly attached. Not pretty but functional and not worn.
I've some outer cables, a steel flat bar, billy no mates stem, no name levers and some v brakes arms (though cant remember if there are pads) Got a functional saddle & some old seatpost pins +seatpost clamp
