Am setting up my own water cooling seup and am taking some ideas from your posts. They have been quite informative and I thank you for the input. I am going a little further with my project as I work in a metal fab shop and materials are really not a problem to get. My resevior ia a 20 inch long piece of 8 inch aluminum pipe with a wall thickness of quarter inch. The pipe is welded to a quarter inch piece of aluminum plate which will serve as the bottom of the resevior and the base for the pump and rad. I have made it just tall enough to fit under my desk. I will keep you posted with pics and the results as I get them. Here is a few picks of the start.
