Cubitek Tank XL-ATX Case Review

I know many of you probably have heard of ATX, mATX and even E-ATX motherboards, but what about XL-ATX?  XL-ATX is a newer motherboard form factor that is mainly used on gaming motherboards.  The G1 Assassin from Gigabyte is actually an XL-ATX motherboard.  XL-ATX boards are just a tad bit larger than normal motherboards and there are not that many cases that can house them.  Well the Cubitek Tank XL-ATX case is one such case.  This all aluminum case not only will house your XL-ATX motherboard, but large video cards up to 310mm and longer power supplies 220+mm.  The Tank also features 4 included cooling fans, tool-free hard drive installation, USB 3.0 connectivity, a VGA card holder and is water-cooling ready.  Let’s drive right in and take a look.

Special thanks to Cubitek for providing us with the Tank XL-ATX Case to review.
