Thanks for the great advise. I'm thinking about going with building a chassis using these: http://www.thecustomsabershop.com/Ac...k-S5-P774.aspx . I want to make battery change out easy, so I'll "bore" out the battery hole just a bit and use a quick disconnect. I'll also probably use several discs so I can mount the CF7.5 and the CEx (modifying as needed).
