i am going to buy this case http://www.coolermaster.com/index.php?LT=e...01Centurion%201

and i was wondering if this window

http://www.newegg.com/app/Showimage.asp?im...-999-550-01.JPG

would fit on the side panel???????

no sorry..
that is a case door to the Antec/Cheiftec Cases...

do you know of any case windows that will fit??????? my antec case window fit on my moms generic case side ...........does it mater wat the brand is???? or if the notches fit it should work right

The color might pose a problem, like car paint all companies have diffrent shades of the same color
Why no make it yourself and save a ton of dough
Or have your original case cover water jet cut to a nice design

Just buy some acrylic from home depot or somewhere else and cut your own window.
