Can anyone suggest a suitable laptop that I could look at to replace my
current laptop that fits the following criteria:

1. Can take 2 hard disks
2. Has a display at least 1600x1200 or better
3. Memory can be expanded to at least 4GB of RAM.

Any suggestions out there? I will be using Linux with it.
