Best computer solution for woodworking environment

Hi all,

I'm helping a friend start up a custom ski manufacturing business and he's looking for a computer to run a CNC router with Autocad. He is planning on having a dust collection system but because of the nature of his business just starting out, space is limited and dust/wood particles will definitely be in the air. That being said, does anybody have any suggestions for the best computer (laptop, desktop, monitor, etc.) or dust protection system that can be used in this type of scenario? Thanks for your help!
