New to building PCs and just ordered my first. Primarily for gaming/school. Anything I missed?

Hello, so for Christmas I got enough to make a custom gaming PC for games obviously but also school. I used a vid on YouTube to get me started. Below is my build. Will this be enough to run on day-one? Do I have everything necessary? I've got windows, and monitor mouse/keyboard already. The case is a tad bit small, I know.I know neglected to buy a wifi adapter due to the fact I intend to use Ethernet, this is doable right? Lastly how easily can this build be upgraded. I don't plan to immediately but I will eventually.

You're good! The mobo has a built in Ethernet, so no wifi card was needed. Maybe get a bigger case, such as a nzxt source 210, for upgradability. Aside from that, happy building!

if you want a better gpu than go for the r9 270 i think there are models that are the same price as the 660 and it has a lot better preformance
