Yeah, it's pretty good but you might want an extra fan or two for that case.
Now, for building it, here's some advice-
You should breaboard. Take the cardboard box of the motherboard and put together your components carefully. That way, you can test them without having to keep going in and out of the case and possibly damaging them.
Next, you should make sure that you use standoffs inside the case. They are little screws, usually bronze, that keep the motherboard off of the metal of the case. If you don't use them, the case will conduct the electricity from the other side of the motherboard and fry it when you turn it on quite possibly damaging other parts too.
Don't force the CPU into the socket. Just put it on the socket, and it'll fall in. Make sure you lock it into place, lol.
And then the obvious stuff, don't bend anything, don't shake stuff too hard, try not to drop anything, etc.
It's also good to have another computer on hand and nearby (obviously you do since you posted this) just in case you need to search for help, etc.
Just be careful all around and everything should be fine.
Your build has pretty good value, btw.
