I don't know shit about building pcs so I need a lot of help with this.

I know this is a bit over budget, but this is what I would build at near your budget...

Prolly could go a little cheaper on case, psu, hard drives, and maybe RAM.

All without sacrificing performance.

Naw, I'll stick with that build. I especially don't like going cheaper on the RAM, PSU or the drives.

As for the case, for what you get...it's already cheap as hell.

Could i get a bigger tower and put it all in? I just dont want to get a size to small and then want to upgrade in a couple years and not have a big enough case

s340 and r5 are both cases that you can use for a very long time.

The mentioned mid tower cases has room for what ever you need.
Even fine for 240mm rads.

I really really doubt you would ever upgrade to eatx+ size mobo.
