I realized the error in my ways, I knew I was forgetting something. The area that I wanted to mount the computer in trunk was not quite as large as I had hoped. I forget to account for the length of connectors. Doh! Luckily I hadn't done any painting and with the help of MR table saw fixed it right up. Here is the slightly more compacted version, rough painted with some hammered texture paint to give it a more metallic look.
