ok things you want
1. a tool for cutting windows
a. a Dermal with cutoff disks. not that great for long strate lines but wonderfull for hard to reach areas pluss its versitile so you can use it for lots of things
b. a jigsaw. good for cuting windows and long strate lines.
c. a drill with 3in hole saw for cutting holes for 120mm fans
2. auto boddy fill. bondo will work, but but i would suggest something along the lines everglass
http://www.evercoat.com/productDetail.aspx?pID=36 its amazing easer to work with and is slightly flexible so it wont crack like bondo will
not sure if ther was any thing else you were looking for but let me know if i can help
