Honestly depends on what it is. I have four pentium pro’s sitting here that at current value are worth about 100 each.

Some parts can be desired in the retro gaming community.

You may be better off doing what I try to do. Fix them up and install Linux. Then give them to someone who could use it. I left a laptop with a dive operation while I was there so they could give it to a school. I installed linux and a few other things and grabbed a copy of Wikipedia so they could take it to a community without internet and still have some access to the knowledge. I threw in a copy of python and rust to support programming as well as some learning applications and videos. I stuffed a 320GB hdd till therewas only about 10GB of free space. I wish I had more to take down but space was limited.
