Consumer review (

Decent box, but not "boutique" quality.


This product is getting three stars because it is loaded with annoyware. Otherwise it's a decent machine for the money. I feel like I paid extra for the smaller form factor and the alienware name, but it's still large, about the size of a small desktop...

Very good performance

Much larger than photos would lead one to believe ; Huge power brick ; Full of useless software and background processes
