“Can this laptop be customized??? I like this laptop but would need to replace the existing processor, storage drives, and Windows with the Intel Core i7-4790 3.6 GHz, Intel 750 400 GB SSD, and Windows 7 Professional. Is that possible? An ad refers to the processor as a “Desktop” processor – will it also fit and work great in the laptop or is it intended only for desktops? If that is not possible, what are your suggestions? I want an extremely fast system, but have to watch my budget too. Thanks! …..Bob”
