Microsoft Xbox 360 Reviewed - CNET
A review of the Microsoft Xbox 360 (20GB) game console has been posted over at CNET. ‘When laid horizontally, the 8.8-pound Xbox 360 is 12.15 inches wide, 3.27 inches high, and 10.15 inches deep, and it's actually slightly smaller than the original Xbox, which also weighed in at 8.8 pounds. Unlike the original, the Xbox 360 can also be propped up in a vertical position and, as you're probably aware, can be customized with interchangeable faceplates that cost as much as $20. Custom faceplates aside, it's worth pointing out that the beige color of the system tends to clash with the silver and black of typical AV components.
One of the reasons Microsoft was able to keep down the 360's weight is that instead of building a standard, desktop-style hard drive into the unit itself, it's gone with a smaller--and more expensive--laptop-style hard drive that's detachable from the main unit. However, unlike the PS3, which accepts any standard 2.5-inch laptop drive, the 360's drive is encased in a proprietary snap-on module. You can upgrade to a larger 120GB model for around $180--but if you're already interested in that much storage, save some money and just pick up the 120GB Xbox 360 Elite instead.’
