Many enthusiasts generally prefer to roll their own rigs, but when it comes to notebooks, the notion of building a system from scratch becomes less practical and appealing. Things tend to get expensive, your build options aren't as robust as they are with desktops, and working in tight quarters will test your patience. That's where system builders come in, and you have three primary types to choose from: large OEMs like Dell and HP, smaller integrators and resellers that specialize in bang-for-buck setups, and custom gaming boutiques like Maingear, that prefer to push the pedal to the metal in order to differentiate.
