Looking for a new project frame.

looking for something in the XL realm, ideally a light XC 29er (hardtail or short travel bouncer) but possibly a disc brake gravel or similar frame. Got lots of bits so aiming for something super cheap/tatty/old so my wife will be proud of me not spending too much! Lol

Condition or even damage doesn’t matter…adds to the project fun!

Anything old and gathering dust? 
Cheers
