Offhand, I haven't a clue as to what "Dimensions (mm) 220 x 580 x 535mm (W x D x H)" implies. I never have memorized the different specs of case sizes. So is this a mid-tower or full-tower case? For the 1st time ever, Tt has actually come up with a feature that I like and should be immediately added to every case I know of, i.e., an extruded side panel to accomodate the wiring. I've tried everything I know, to no avail, to get the right side panels to fit properly on all of my cases, with all the wiring behind them. Every single one of them bulge out letting any stray dust to be intaken. The worst ones I have with this problem are two Corsair cases. A 700D and an 800DW. This is irritating beyond all reason, especially with such expensive cases. The inside of the cases appear immaculate as to the wiring that is almost entirely hidden. But the sides bulge outwards and sometimes pop open, scaring the crap out of me. Tt has evidently solved this problem. I can no longer hate on ThermalTake. Just dislike all of their products with a passion. There is a difference. Other than that, this case appears to be Tt's copy of CoolerMaster's HAF-X. Whatever size this case is, it's as ugly as my HAF-X, but at least nobody would be fool enough to steal something as ugly as either of these cases.
