Not trying to take away from your post or anything but you should probably lower your price. You can get a brand new ghost from amazon for about $420 aud with shipping included which is already a pretty steep price to swallow but at least you get some form of warranty/ amazon return coverage.

Also I know the steck is slightly lower in quality but its basically the exact same case. Its on sale right now for $220 aud with free shipping directly from nuovolos site here: https://www.nouvolo.com/collections/featured-products/products/steck-v1-1-base-unit

BTW because this is a boutique case you might also want to actually provide pics of the case itself instead of just the box.
