what should i use to attach a window to a door, i was thinking of using rivets?

Rivets are good thats what my window is attached with and the have a clean look, but theyre semi permanent. However u can drill them out if u needed too. Screws are good too if u do them right, or u could use an adhesive.

Rivets or screws would look cool especially if you got them anodized or painted to match the color scheme of the case...

rivets, screws, caulk, double-sided tape, velcro, H molding (w/ locking strip), and more...

if i ever get around to puttin a window in my case i will use rivets

for a custom look use 2 sided tape it works great.
