Yup, the m998 (or the Global Win that it's base on)are about it in the states and it's a maxi mid (decent price now) - small box would stick you with an 80- maybe 92mm fan at the rear. Look at the Raidmax Smilodon or Spire Pininfarina if you want mobo tray features in a smaller case. And I may have a line on a twin to the Kingwin 424 and I have a new Wave Master for sale in my FS/T listing linked below if you don't mind working on the cooling a bit.
