Best type of window

I'm cutting out a window in my case, probably not getting a kit. So..whats the best to attach it?

I was thinking just some screws, but I'm wondering if there any disadvantages to that method? Also any suggesting to attaching a window?

Thanks

Well using window chaulking, silicon or double sided tape would be the easier and cleaner way, but if you take the time to secure it with some big really nice looking bolts...it'll pay off.

i prefer the look of bolts too. also, i have plexi glass for my window... i've heard that acrylic doesn't create static electricity, so it is a better way to go if you can... i would have gone with acrylic if i could've..
