A:Answer Hi AnDy,
It is possible to upgrade the 120GB SSD to a 1TB SSD. As long as you already have a 1TB SSD, you can swap out the 120GB SSD that this system comes with. All of the systems on Bestbuy are set configurations, which means, any specs you see on the page is what you will be receiving. Upgrades are always possible, but an upgrade will have to be purchased separately.
