Not bad anyone else?

Here's some ideas for the base, depending what sort of system you want.

The processor you choose has to match the base system.
On top of that you need memory, graphics card, hard drive, optical drive and floppy drive if you want one. Keyboard, mouse and speakers needed too if you haven't already got them.
