Alienware's M15x is a behemoth. While it can be carried from place to place, this is absolutely a desktop replacement at a thumpingly huge 4.08kg. This is the 15.6-inch, 1920x1080 model — the larger M17x is a crazy 5.3kg, so in a way we should be thankful.
Alienware's unique love-it-or-hate-it styling is here: a combination of matte black and metallic red, although you can also choose to have a black or grey exterior. A huge amount of things light up as is the Alienware way, from the alien head on the lid, to the logotype and alien head under the monitor, to the status indicator lights, the headlights on the lip of the laptop, the outline around the touch pad and the backlit keyboard. All of them can have their colours customised through the included AlienFX program, or even turned off if the bling annoys you.
Due to the pure size this thing has everything — VGA, HDMI and DisplayPort out, three USB ports (one with integrated eSATA), ExpressCard 54, FireWire, SD card reader, gigabit Ethernet, dual headphone jacks and a microphone jack that can be re-purposed to 5.1 sound outputs.
The internals are of course insane — a Core i7 Q740 @ 1.73GHz (that can reach 2.93GHz under turbo boost), 8GB RAM, 640GB 7200rpm hard drive and a Radeon HD 5850.
