I have just thought of a great idea.
Taking this idea: http://www.mini-itx.com/projects/briefcasepc/ > http://www.mini-itx.com/projects/briefcasepc/ and modifying.

Instead of using a Mini-ITX board, I am going to use a Standard ATX Board. I will use a 1U(Rack) size 300W Power Supply. I will use parts that I already have at home.

Intel Celeron Processor @ 466MHz.
256MB SDRAM
20GB Hard Drive
Aluminum Briefcase ($30 @ Home Depot)
SLED (Extra one that I have but will create my own docking connector).
15" DELL LCD Monitor
4 Port 10MB Hub

I am going to allow the Empeg/RioCar to slide in/out of the PC with a Plexiglass door on the front of it so that it is protected.

It will be easy to put together, the hardest part will be making it look nice. I suppose that it will take me 2-3 weeks to complete this. I will then post pics of what it looks like.

Ques: How do you post inline pictures like I see on other posts?
