Guys I have an Old CPU and Monitor. Is there a place where I can sell this? Or is it just scrap?

This is an 18 Year old CPU and monitor. Specs are - DDR2 Motherboard. Intel Pentium 4 Processor. 2 GB DDR2 Ram. 1 GB Nvidia Geforce Graphic Card. 250 GB of Storage. Even though its old, its in very good condition. It has XP in it and runs smooth without freezing. Everything is working properly, The CRT Monitor and Disc Drive of the CPU despite being old. Not to brag but I maintained it well(Excuse the Dust though). Over the years....the only trouble it gave me was its PSU which I replaced from time to time(4-5 years). I used it for gaming and general computer stuff. The highest graphic game I could play in this was GTA 4 (that too in low settings). I am not sure if I would get anything for this. Hence asking. I bought a new PC and don't need this.
