Is this Laptop going to be decent for gaming?

[Suscar]

I'm not familiar with the specs of laptops/pc's etc, so I'm not sure if like 4GB ram is good for light gaming or if 2.17ghz is also good for light gaming. Also, is Intel pentium a decent processor for light gaming, and does anyone have any clue what kind of graphics card or processor it has? (By light gaming, I mean something like minecraft on medium-low settings). Here's the link again, http://www.amazon.com/HP-15-R011DX-15-6-Inch-Pentium-2-17GHz/dp/B00LD88UZK.

Thanks.

Also, am I able to change the GB of ram it has to six and am I able to change the kind of graphics card it has if it's not that great?
