Proper Disposal of Legacy Dell Laptops

Good Morning,

I have two legacy laptops, first one from 2000, and second one from 2003:

Dell Inspiron 5000e
Intel Pentium III processor
597 MHz
128 MB of RAM

Dell Latitude X200
Mobile Intel(R) Pentium(R) III
CPU – M 800 MHz
797 MHz, 376 MB of RAM

For each system please explain

1. How to locate the hard-drive

2. How to remove the hard-drive

3. Best way to destroy the hard-drive (i.e. with a hammer)

4. How to dispose the remaining laptop

Last month I purchased:

Dell Inspiron 1545 (Ubuntu 9.04)
Intel Core 2 DUO T6600
2.2GHz, 800Mhz, 2M L2 Cache
4GB, DDR2, 800MHz 2 Dimm

Next week, I am hoping to purchase Mini 10v with Ubuntu Moblin to take to work, running errands, etc.

Thank you in advance
