Just on a side note, if you're not dead set on that keyboard + mouse you could get something better from logitech, corsair, hyperx, or some other brands. Razer is known to be overpriced in relation to quality, and in my experience very unreliable. I had Naga mouse and it was just a pain to get used to it in the first place due to its awkward design (trust me, it seems like a regular mouse but that arch makes it very weird to handle), then about a year later right click started acting up and I pretty much had to buy a new one.
tl;dr if you don't need any flashy design elements and you value performance, get something else.
