Dell's just come out with an
innovatively-designed new gamer machine in their Alienware series: it's vaguely hexagon-shaped, preventing you from placing it against a wall and decreasing its ventilation. Looks cool.
You'll notice the angled corners and somewhat of a triangular shape (with twice as many sides). According to Dell, you can place the Alienware Area 51 against the wall and not have to worry about thermals getting out of the control. That's because there's a controlled gap and a sharp angle that ensures only a small part of the system actually rests against the wall, whereas there's still plenty of room for hot air to escape up and away.
This design also offers users easy access to rear ports, though if you need more room, you can rotate the chassis like a ball so that the rear is facing upward instead of an at angle. Another advantage to all those angles is it makes the occasional transportation chore easier -- there are more places to grab hold of compared to a traditional desktop.
Slashdot
linked to it and got tons of flak about it being a Slashvertisement, but I think it's cool hardware. Have a look: what do you think?
And it will look a lot less elegant with a bunch of wires poking out of the top/back.
