@Mick64+This case design looks awesome! Is the front intake fan 120mm or 92mm? I kinda hate 80mm intake/exhaust fans. I personally think you should go aluminum, personally I would never buy steel again. Have you checked out WiNDY/House of Sloldam cases? Some people are willing to spend $500 or so including shipping on those cases and some of those MM and Silverstone cases aren't cheap either.

I think you should at least look into production costs, even though you are Uk based I would still be interested (I get huge int'l shipping discounts so i don't take quite the hit on shipping). I'm have an extremely difficult time deciding on a case myself right now grrr. Great work!
