Do I need to build a "gaming" computer?

I decided to stick with Windows 10. I did like 7 better but I can't convince myself to go backward.
I've been looking into each part over the weekend and changing a few things here and there. I'm starting to go for a blue/white theme now I noticed. And I came across this motherboard

It's cheaper than the one you suggested (which for me is actually a concern. Usually I associate cheaper price with less quality when it comes to electronics sometimes) but from my comparison it looks like it's all the same specs I think? Let me know if I'm missing something.
I also changed out the case (just to match with the theme) but I don't think this subtracts from anything the cooler master one had. This one also seems to have a nifty cable management thing to it which looks convenient. And also 3 out of the 5 available case fan slots seem to be filled up with fans by default which is nice.

I'm probably going to order everything in about two weeks so of course now I'm starting to second guess/micromanage everything at this point...But I have to say it is kind of fun looking up everything and comparing/contrasting.

Also, let me know if I'm pestering you at this point. I'm starting to feel real self conscious asking for all this advice/input. I usually just do everything on my own and screw up when it's appropriate.
