Just to say that my lounge gaming/HTPC has been in a Silverstone Grandia case for the last four or five years and it has worked well/not been out of place in the lounge. Tried a variety of normal-style remotes over the years but usually just use a Logitech k400 wireless keyboard/mouse for HTPC control and made a lightweight kidney-shaped lapboard which can fit a proper wired keyboard and mouse/mouse pad for gaming.
My previous case was an Antec Fusion case which looked nice and was well laid out but just wasn't big enough after upgrading components - went with the GD09 because it could fit in a full-sized card while still pretty much matching my amp size-wise.
I would probably consider water cooling it if you were looking for quiet with those power requirements.
