Who likes wearing stuff on their head while gaming? Will be uncomfortable, unsociable. Perhaps even eye straining. Sometimes you just want to turn your head left but you don't need the display to also do so.
Since trying the Rift DK2 myself, it has become VERY easy to spot when someone hasn't. Comparing VR to 3D is the definition of unfair. The immersion aspect changes EVERYTHING. You'll see for yourself eventually I hope.
No but that's not the point... the whole point of having a window (and many people do), is to be able to see your components. The fact your're not looking at them when gaming is irrelevant. It's like saying what does it matter what colour car you have, or even what it looks like, as you don't see it when you're driving.You dont look at the case when your gaming mate.
Given how 'special' the Fury X is shaping up to be, I want to see it in all its glory... not some cheap matt plasticy back with a load of stickers over it. That's criminal in my opinion. I'd seriously consider buying a case that shows it off as it deserves to be.
