Alienware announced refreshes to both the design and the technology of its high-end Area-51 and Aurora gaming desktops. A new angular look replaces the familiar rounded alien-head shape of the old models, and features such as motorized air vents and specialized hard-drive layout give Alienware some different selling points. Alienware is plus the previously unnamed OEM that purchased the first batch of AMD’s Radeon

HD 5800 cards, so other system vendors can blame Dell/Alienware for their short supply and delayed order shipping.

Essentially, Alienware has two systems to announce today: the full tower Area-51 and the micro-ATX-based Aurora. Each system plus has a more expensive ALX edition that features liquid cooling, a wider array of case lighting, and other tweaks.
