Thermaltake introduced their Core X Series back in January at CES.  The case that really eclipsed the others out of the series was the Core X71 full tower, but let's face it, most people do not have the need to such a large case.  For most of us we want a mid tower that has ample space inside, great cooling support, and looks pretty good.  Well look no further as today we have Thermaltake's Core X31.  This mid tower has room inside for long graphics cards and power supplies, two 360 mm radiators, tall CPU coolers and much more.  The motto of the Core X Series is ?Your Build. Our Core? and Thermaltake really stands behind this as the internal components of the case can be removed if you don't plan on using them.  Let's jump in and see if the Core X31 is the perfect mid tower for you!
