Inwin always makes these interesting cases. I have only ever liked the look of the H-frame. Not my cup of tea, but the idea of using that material for a window in a standard case does sound cool.
Its inwin, it'll either eat dust like no ones business or fall apart in a few mins of usage. I think the tech involved in this case would be cool as maybe a side window on something like a cm storm case.
If you really want a stupidly expensive case you from them you should get the form over function that is the new £1000 H frame King. Now that is a case with a difference, a huge noisey dust inhaler, complete with a huge side window and edges to cut meat on.
That case is weirdly in a color scheme that was exactly like a person who painted his rather poorly, thus causing the biggest argument I've ever seen on the forum. xD
