Antec 1100 Chassis Review @ OCC
 

Taking a look at the sides, I'm quite happy. Personally, I love chassis with large windows – I like to show off my running hardware, even when it isn't all that impressive. On the Eleven Hundred, the window takes up over half the side panel in width and nearly the full size in height. It also includes two pre-drilled 120 mm fan spots for the addition of your own fans and aid cooling without hampering the view too much. The other panel behind the motherboard tray has a single 120 mm fan location for cooling from the back. This is perhaps one feature that most chassis still don't provide today. It's a simple addition and placing a fan here should bring your temps down even more.
