Just had to try it ...
Futro S400, Motherboard 8TR53A0XF118, BIOS 4.0.0.Q
(Update 20 NOV: TECO TR53A0 Motherboard)
1Ghz AMD NX1500, 1 GB RAM, Gigabit NIC, 4 USB-2 ports.
Update 20 NOV: Processor scales up and down nicely.
OMV installed on a SanDisk 8 GB, with attempted reduced logging.
Mounted two external USB disks.
Although the mb provides an IDE-connector, the only other thing that will go into it ... will be a fan ...
(Update 20 NOV: Still waiting for the fan to arrive, could only get 12V, wonder if it'll go with 6V).
(The box on the left is actually a NAS in itself, but here used as an external USB disk
Never really used the thing, but it does NAS and USB, and it takes both IDE and SATA-disks).
Final hook-up planned to be just the disk on the right mounted.
It does SMB/CIFS and OpenVPN nicely on this side of my router.
(Update 20 NOV: OpenVPN runs from the outside, through three routers.
Not fast, but that's what you get from an ISP-connection at 10/1 MB/s).
(20 NOV: Not very informative pic removed ...)
