You can get about £11 for it on websites like
https://www.sell-your-laptop.co.uk/
(don't know anything about that website - but put in typical details...).
Probably no point.
You could use it as a photo frame? For reading recipes on in the kitchen (doesn't matter if it gets splashed). As a web / file server / for backup purposes. For streaming movies through onto a TV (no idea how powerful that laptop is - haven't looked it up).
I used to use old hard disks as coasters. Might be something you could use the Palm Pilot for? Or take the laptop apart and use the screen as a place mat...
