It's not a bad looking case, I would assume it will be available in multiple colour schemes. Needs to be a reasonable price though, IMHO a case with a steel frame and plastic fascia needs to have something a bit special about it to break £80.
I'm assuming it is a prototype, no grommets in the cable routes, no dust filters, hideously inefficient grill to place a radiator behind in the roof, no tool less fittings in the 5.25" bays, front cages for HDD look like they are fixed in place and steel plate with little airflow facing the front of the case behind the front intakes.
Depending on price and release features that are corrected these would have a massive bearing on weather this would be worth investing in, on the face of it though it's a decent looking case. Antec really changing the design direction finally?
