[citation][nom]menigmand[/nom]I love a small, quiet pc, but the biggest problem is not the actual size. The main aesthetic problem is that a pc setup will still include a monitor and plenty of wires, a keyboard and a mouse. Having a pc in a small livingroom tends to "take over" the space and make it seem a bit like an office. That's why I like to game on a laptop, even though I get less graphics performance, the kit can always be folded up and put in the cupboard when I have guests over and need the dining table.[/citation]
The only wires that need to be hooked up to this thing is HDMI for audio and video output, and power.
Put the tower beside the TV so that all your wires are hidden behind the entertainment system, and the keys and mice can hide in the coffee table if you don't want them out.
Internet is wireless, keys and mouse are wireless, game pads and joysticks are wireless, and while you CAN hook up a ton of other periphrials they are entirely optional. If your HTPC or gameingPC takes over your living room any more than a cable box or game console does then you are doing something wrong.
