I posted in flames about buying my friends PC for $300 or so and now he wants to see if I'd like to buy his old Alienware instead. He complains it weighs too much ( around 30 lbs ) so I'd just use it as a desktop essentially.

It's an M17x, I know it's nicer but I'm not sure how upgradable it is being a laptop and all.

He said he'd take around $500-600 for it.

Go with a desktop instead that's semi dated, but the case/psu/hdd's are still dope?
