The Antec 902 is a great case i have one.
Excellent build quality and cooling.
Problem is the USB3.0 is cable pass thru to the mobo rear ports.
The Corsair is a newer case and the USB3.0 plugs directly into the mobo 19pin header.
If your mobo has that feature some don't.
Both are great cases.
Buy whichever case appeals to you most..
