Antec released the Performance One Series P280 earlier this month. With it came many updates that fixed many issues some users had with last couple of Antec cases. Today we get a look at the Eleven Hundred; it is the newest addition to the Gaming series. The Eleven Hundred is a Super Midtower, so it's slightly larger than a standard midtower but is not quite a full tower. It's meant to fill the gap between Antec's Twelve Hundred and Nine Hundred.
