Probably, if you're comfortable with a screwdriver and some cables and wires. If you've ever worked with electronics in a car, it's not all too different (and is probably easier) and if you know how to plug and unplug wires from TV's and game consoles, it's not that much harder.
The thing to remember about SSD's though is that they're smaller than regular 3.5" Hard Drives. If you're installing into a desktop, you may need a 2.5" to 3.5" adapter to fit this 2.5" drive into a 3.5" desktop slot. Newer cases may have 1 or more SSD slots, but older ones generally only have 3.5" ones.
If you're installing into a laptop (provided that your laptop allows you to swap out the drive) PNY includes a spacer in the box that allows you to fit this 7mm drive into 9mm drive spaces.
Still, if you're going to try something like this, I'd lookup some youtube tutorials online or better yet, find someone in real life to help you that knows about computers. Once you're shown the ropes by a mentor even a few times, it becomes easier after that.
