I sold my old Duron chip and mother board and RAM. I got 18$ for these. Just two years ago the RAM cost close to 100$ and three years ago the motherboard and chip were about 300$. I got about one full year of use of these parts. The computer these were from was my 16th personal computer. It did not last long. It was frustrating later on in its life. I am left with the case, hard drive and floppy drive now. I can now buy it a new motherboard and chip and RAM, if I have time and money to do this.
