Specifications of My Computer DELL Inspiron 8200

A brief history of my computer. Bought in the year 2002, and i have been using it since then.
From day one until now, i have upgraded it's ram from 256MB to 640MB and upgrade the HDD from 20GB to 80GB and also bought a new replacement Battery Pack, as the old one died.

May consider replacing it's 128MB ram module to 512MB so that the system has 1GB ram.

And may also consider dismantling the machine apart and clean it up then assemble it back.
Here are some links to DELL's documentation, in case anyone else need to dismantle the machine.
