Unfortunately, Bay Trail doesn't support SATA port multipliers. If you want to be crafty, then mini PCIe -> full PCIe -> SATA card might work.

I wouldn't be too concerned with quality. As long as it has the right parts installed, it should work. This is a 10W SoC, so it's not like it needs the world's best VRMs.

Thanks, glad to know bay trail doesnt support port multiplier but good tip about using mini pci, ive also considered using USB3 to esata/sata. This idea came up as I thought the m3 version of the Intel Compute stick may be an interesting solution if I could run the hdd's over USB3 and find a way to power the stick, would also take care of the msata/m2 drive as its have a drive built in for the OS. main conern would be usb3/esata working and the core m3 being powerful enough for Plex server (at most 1x 1080p transcoded stream, likely no transcode though).

for mpcie this looks like itd fit the bill and isnt breaking the bank

Controller has "asmedia" on it so it's awful, but it should be enough for a media server.

How much processing power do you need for a Plex server exactly? I'm starting to wonder if a quad-core Atom is a bit overkill and you should be focusing less on the CPU and more on the SATA controller.

How much processing power do you need for a Plex server exactly? I'm starting to wonder if a quad-core Atom is a bit overkill and you should be focusing less on the CPU and more on the SATA controller.

It depends. My server is an i5, which is probably overkill. Essentially id like the finished "product" to be able to run Windows server 2012 r2 essentials and run client backups, perform downloads, file serve, and act as a Plex server. If Plex doesnt have to transcode on the fly the CPU requirements arent that high, if it does have to transcode on the fly it then becomes a factor of the resolution and bit rate being converted along with the number of different videos/streams being converted at the same time. Im not expecting much transcoding if any to be needed, so I think CPU's in this class would be ok for that, just not sure how well they will handle the rest.

Essentially what I need is a board/controller that can feed the RSV S4's backplane (or potentially connect direct to 4x sata drives without the backplane) and still have a msata/m2 for a OS drive or built in storage like the compute stick for the OS. Your idea about using the mini pcie for sata with port multiplier was an excellent idea and may be the easy solution to this as I would not use a wifi card in this).

Really everything at this point is just theory, I have to open it up when I have a chance and see what room I have to work with. The first milestone is evaluating if this is possible and viable to do on the cheap. Im willing to spend up to $200 to get a working machine without drives, but any more than that isnt worth it. Essentially in the end I would be looking at recouping whatever money I put into it. Id be doing it for the experience and fun of it, as I think itd turn out to be a neat project/mod

Ok so Ive unpacked the old RSV-S4, opened up the case and checked it out. Have come to a few conclusions.

Overall I think this is very doable. mITX will not be an option. Clarence will be about 5 inches across in width, 8 inches length, and 2 inches vertical clearance. So a nano itx with a height lower than 2 inches will work.

As for connectivity I was surprised to see that the backplane doesnt appear to have any proprietary type connections for the major stuff. It takes 2x 4 pin molex for power, 1x sata for the data. The built in fan uses a small 2 pin connector that goes to the backplane. The front LED's have a ribbon cable that runs to the backplane. Id presume the fan and LED's would continue to function if I use a motherboard and keep the backplane.

So basically to do this im looking at:

-Nano itx board, 5"x5"x2" (W x L x H), likely need it to use a DC PSU...not sure will have to think on how I will power it.
-Cut out the built in PSU
-Cut the back for the MB I/O ports

Id need to figure out how I will power it.

If the board i get doesnt have sata with port multiplier (which i assume i need) i can either try for a mpcie sata card that supports it or use a USB3 to sata/esata adapter (i have one that should support this). So I have to figure out how ill connect the drives.

I will need a couple of drives to test it.

I may consider trying to improve the cooling by seeing if i can fit an extra fan or 2 in?

So I think this thread has helped me get started. Looks like nano itx motherboard is my best bet. Im not sure why, but something really caught my interest about the possibility of having a 4 bay server in an enclosure measuring 5.3" x 7.1" x 10". I figured I have this enclosure sitting around im never going to use, might as well tinker.

The RSV-S4 has a 150 watt psu built in, and I think to have everything work my best approach is trying to feed the motherboard from this instead of trying to use a different PSU.

The built in PSU has 2x molex that power the backplane. Im wondering if its viable to use a cable that has molex pass through and dc 12 to goto a motherboard thats dc powered. The cable would be something like:

https://www.dazmode.com/store/product/rgb-controller-dc-to-4-pin-molex-adapter-cable/

Are there any obvious issues with splitting molex off to dc that im missing? Imo 150 watts should be enough for 4 drives and a nano itx platform.

If anyone has a better approach let me know. Thanks
