"What I received in the box when the window arrived was, of course, the window(8 11/16" x 11 1/8" or 22.07cm x 28.24cm), window molding (3ft), a locking strip(3ft), a washer, and instructions for installing the window. The instructions were pretty good and went through each step, though, somewhat vaguely at times(could've had a "troubleshooting" section :), but I was not able to follow them "exactly" the entire time...but we will get to that. The first thing you need to do is decide where you want the window on your case. I chose as far left as I could get without cutting into the handle, and high enough to easily see the processor yet low enough to see some of the installed cards.
