Custom boutique PC builder Maingear has sent us a couple of high-end desktop systems in the last year. The Maingear F131 was pitted against the Puget Deluge Mini and the Acer Predator in our sub-$2,000 gaming desktop roundup of 2010. Then late last year we had a look at their Shift Gaming PC, a beautiful no holds barred $7,000+ triple SLI overclocked monster that any hardware enthusiast would love to own.Today we will be looking at the notebook equivalent of the above mentioned Shift desktop system, known as the Titan 17. Considered a desktop replacement by Maingear, the Titan 17 is their most powerful notebook to date. With measurements of 16.5” (w) x 11.3” (d) x 2.2-2.4” (h) and a weight of 12.1 pounds, the Titan 17 isn’t a system you want to haul around on a regular basis like you would an ultraportable or netbook.
