Another question...... regarding certain items.

Did a search for this, didn't come up with much......

I've come across two rather large, space heaters. Both of them work, but, I have no need for them, and of course, no one wishing to buy them.

The main body of both are pure metal, with metal protective grills over the both of them...... should I take these things apart to get rid of the plastic pieces, or leave them as is?

Also...... computer parts...... I have about 10 DVD/CD Rom drives that either do not work, or are barely working, that I've collected over the years..... along with various other computer parts such as completely gutted cases...... motherboards, power supplies, etc....... Anything I need to know about these particular items?

Thanks as always for the help!
