Depends on what you have available.
Newegg has purpose built NAS systems for as low as 60$.

But if you want a decent turn key solution you'll need to spend about twice that. Getting a NAS with less than 4 drivebays is probably not a good idea. I'd recommend buying a bare NAS and drives, since NAS with drives tend to be overpriced.
If you are willing to put some work in it and have an old computer lying around you can just use freenas or similar software to build your own. There are professional grade systems pre-built with freenas but they tend to be expensive (like 10 times your budget expensive). For a single user you don't need much in the way of hardware so if you have a 4-5 year old computer it should work just fine, but preferably use one that can support a lot of drives.
E: "Did they... did they just endorse the combination of the JSDF and US Army by showing them as two lesbian lolicons moving in together and holding hands and talking about how 'intimate' they were?"
B: "Have you forgotten so soon? They're phasing out Don't Ask, Don't Tell."
