This is the build (https://www.youtube.com/watch?v=S6FD1b-tYkk), please take the time to watch it as I am not very knowledgeable in computers and need input on this build before going out and building the components.
It seems fine. A big part for saving money can be getting a CPU that runs double-duty as a GPU, as long as you aren't planning on playing Battlefield on High setting. Both AMD and Intel have these; just make sure whatever motherboard you get supports all the parts you're buying for it. Research is key. If you don't just rush in and buy a bunch of pieces somebody told you to get, you can instead take your time learning what is compatible (and why), and you might find something twice as good as you planned on getting for only a few dollars more (just because the new version came out does not mean the old version got a price drop).
You don't want your rig to go out of date in only a year because you just bought what was cheapest. Find out what technologies are coming out soon and ensure your parts can run it (like, the next DirectX).
For every piece you look at, read lots of reviews. I suggest reading them on Newegg or Amazon. Doesn't matter if one person told you it's the greatest part ever, it might have a common issue or compatibility problem with another part you're getting, and there are usually negative reviews that point it out and sometimes tell you how to avoid/solve it.
Go with Seagate hard drives, they're better than Caviar, they might be a little bit more expensive, depending on where you shop, but they're known to last longer. 8GB Memory is sure as heck enough, I have 16GB total and it's all fine. Cases don't matter much, but you have to install extra fans depending on the heating. Also, DO NOT OVERCLOCK, this voids the warranted parts you overclock and the manufacturer or company you buy from won't replace them, and I think the normal GHz is enough speed for what you want.
