Apple, HP and MSI aren't the only ones big on super-stylish, trash can-shaped desktop PCs. Samsung has quietly started taking pre-orders for the ArtPC Pulse, a cylindrical computer that bears more than a passing resemblance to the current-generation Mac Pro. The two systems couldn't be more different in terms of focus, however. While the Mac is aimed squarely at workstation users, the ArtPC is most definitely intended for home use. Its centerpiece is a top-mounted, 360-degree Harman Kardon speaker with ambient lighting -- much like HP's Pavilion Wave, this could sit in your living room just as easily as it could in your den.
