Dell (got one, have you?) has decided to try and compete with the likes of Alienware for the high performance games PC niche. The new Dimension XPS line is geared specifically towards the likes of us, and is described as their most expandable and powerful system to date, with optional RAID arrays, a taller, funkier case (a clear nod towards Alienware's offerings), USB 2.0 and Firewire support, and a 460W power supply.

Dell's European website hasn't been updated with the new Dimension XPS line just yet, but given Alienware's recent appearance in these parts, you can expect to see them soon enough.
