You'd have better luck asking in the server forum. I'm already going to hazard a guess that $1,000 is a little low to get this kind of build. The HDDs alone will cost you around $700 for 8 TB. You'll still need some kind of case and PSU, which that'll likely add another $100-150. Then you'll need RAM and an OS, which together will cost you between $150-250, depending on the amount of RAM. Right there you're already at $1,000 and you haven't even got a CPU or board yet.
