Personally, I'm a big fan of using Linux to build LVMs of JBODs. Its the most flexible and extensible solution. You can even add md to the mix and do raid configs but the point is that you'll get growth out of such a configuration.
I see two type of deployments which I'm also considering for myself since I'm at a crossroads too. You could either built this as a traditional "box" or do something more interesting by using an SBC like a Banana Pi
(onboard sata port) or ODROID XU3 lite
(usb 3.0). There are plenty usb 2.0 option as well. For SBCs the issue is the enclosure but there are quite a few 4 bay units about there. 2Tb are getting pretty cheap so a 8Tb system is not out of the realm of possibility but you can certainly grow into it slowly. On the other hand, an advantage to going the traditional route is that a mini-ATX or full-ATX case will give you more bays. Its a more self-contained solutions and allows more JBOD options since you could have a mix of technologies. In this scenario you're back to worrying about fans and noise levels as well as a typical server power consumption.

Subject: [PLUG] Restructuring home network and building a storage server
So, the machine I've been using as my storage server has died, and I'd like
to use this as an opportunity to rationalize my home network setup. At the
moment, it's an accretion of various requirements and bits of functionality
that were slapped together based on what I had available.
[A external router/wifi]
| | |
[B workstation] [C server/VPN] <D Roku, etc.>
[E internal router/wifi]
<F private network>
I use a third-party VPN provider due to my ISP's habit of building
marketing profiles of its users based on browsing activity and DNS queries.
Unforunately, the performance of this VPN cannot keep up with the speed of
my connection, so some nodes have to live in the DMZ.
(A), the external router, connects directly to my ISP, and provides Wifi
that is not routed through the VPN.
(B) is my most powerful machine. It is too inconvenient to keep it behind
the VPN server. When booted into Linux, it opens its own connection to the
VPN provider. When booted into Windows (for gaming purposes), goes straight
to the Internet. (Steam downloads are way too slow, otherwise.)
It also runs my Plex backend, as it can easily handle the transcoding.
Unfortunately, that means that I can't be playing a game while someone
else is wants to watch something off of Plex.
(C) is the server that just died. It kept up a connection to the VPN
provider. As the only system in the environment that could be relied on to
be up, it also acted as the storage server. It has four or five drives
crammed into it that need to be rehomed into a new server.
(D) Are various streaming clients and video game consoles (Roku, XBox,
Android tablets while watching video) that need a full-speed connection
to the Internet.
(E) Provides wifi (and wired connections) routed through the VPN.
(F) Are various nodes that go through the VPN...a workstation, and tablets
when they aren't streaming Netflix.
As can be seen, this is a pretty cruddy design, and the death of (C) is the
excuse needed to finally get things in order. [(C) was also a pretty
annoying box...loud, high power-consumption, and after a fan died the mobo
wouldn't detect the new fan as actually present, so I had to find a
keyboard to connect to the box just to hit 'F1' every time it rebooted.
I'd really like to get the Plex server off of (B). I need a new storage
server to replace (C). When I was first cobbling this setup together I was
going to put (C) behind (E), but (E) is a commodity wifi router, and
there's no way its CPU can keep up with high-bandwidth VPN. And, of
course, devices like <D> would like to stream data from internal as well as
external sources. Letting them access <C> directly is kind of cruddy from
a design perspective, but it got things working fast at a time when I didn't
have many cycles available to spend on non-dissertation-related tech
So, my primary immediate goal is to get a new storage server built. I'd
like to be able to drop the four or five drives I have directly into it
right now, with the ability to put in as many as possible further down the
road. It would also be excellent if I could get the Plex server moved off
of (B) and onto this new box.
My secondary goal is to sort out the VPN stuff. Ideally, I'd like a small,
dedicated box of some sort that can actually push though traffic that'll
keep up with my ISP connection, so I can move more devices behind it and
actually change the pseudo-DMZ into a setup where it only has a tiny box
or two for hosting things that I really want to be able to access
externally, with everything else behind the internal server/firewall.
Hardware recommendations (and architectural thoughts) will be appreciated.
I'm also interesting in best practices for the software and configuration
aspects building a flexible, high-capacity server for home storage.
