I'm thinking about buying an HP Envy 17. I like its specs but unfortunately it doesn't come pre-equipped with an SSD. If I'm reading this HP manual correctly, it has a secondary SATA drive slot that's customer-replaceable. (Since the laptop config for my specific model only lists one drive, I'm assuming that it'll be an empty slot.) Here are some relevant parts from the documentation.

About the secondary hard drive
I rarely perform hardware upgrades myself before so I'll need some advice. I'm eyeing a Samsung 840 EVO SSD (120GB). Will I be able to install this drive in the primary slot and move the pre-installed drive to the secondary slot? Would I need any additional material to perform the installation? (An anti-static wristband? Certain cables/brackets that are sold separately?)
