I need to get rid of a case I have which I am going to mod with a side window. The case is similar to this one: http://www.colorcases.com/cases/0107.html
except it is gray and black. See the link for more details on the bays and slots. It is in good condition except that some of the screw holes by the PCI slots are a little stripped. The window would be a standard clear acrylic window with black molding. I would just charge for shipping and a little for the window. I would say around $40.
