Single Board Computer of the Year
 

The "Open Source" requirement has been removed this year.

Raspberry Pi 3 B!

I agree. Mine is running CentOS 7 and functions as a gateway router (wired and wireless with QoS). It started out as an experiment that turned into a great success.

Voted RPi3B - bought two this year, for the price, very good as a desktop replacement, as long as you're not expecting it to be fast, especially online, but it is adequete. :)

I love my Udoo x86.

Odroid C2, I have one running in a data center in Czech Republic. Uses less than 2 Watts, has a emmc drive attached as well as sd card. Set it up for full encryption using luks.
If it reboots, I ssh into to it using password and id_rsa key, -remote odroid than terminates shell, ssh again (after it reboots). This could be the future for those who do not want to share hardware on a vps.

Working flawlessly for 6 months. Lots of storage and cpu power.

One thing though is I failed to disable the serial port at build.

more so since intel's recent meltdown debacle, which affects virtualised systems severely.

Ti-86 or HP50g or Archos Elements 97* Platinum or Samsung Galaxy S3 (runs Replicant, the fully Free/Libre Android)... also would like to try a ChuWi Hi10.

Maybe these aren't what some people assume/associate for the term 'single board compuer' (SBC,) but as far as I know, these have a single circuit board (exception may be the Chuwi if you count circuits in the keyboard.) So, they're mostly/all single-board portable computers, not SBC desktops (which is what I've seen the term used for, but isn't everything.)

Most the original post's list sounds obscure, and some, maybe so underpowered I wouldn't have wanted them around 2000 AD/CE. What about decent-/very-powered high-quality system manufactures like & well-known Intel NUC, ASUS VivoMini (top-quality, customizable,) HP ChromeBox (well-known, customizable,) even old--if open/crackable (to install FLOSS)--Apple Mac Minis? Very surprised not even one these is listed.

I'd kind of like to see a desktop SBC with 786 (pentium 3, K7, etc.,) NVIDIA GeForce3 (two, or another graphics chip, can't remember,) SB, GUS & IW, EWS64XL chips all in a tiny box like the size many SBCs are becoming.

It's a strange question though. If I remove all PCI(e) cards from my workstation tower PC, it's a SBC (as are dozens of categories) according to Wikipedia.

not quite.
one of the defining features of SBCs is that components are not plugged in, but soldered on: cpu, ram, gpu.
not that that's a good thing, but i guess that's what makes them much cheaper and - tadaa - smaller, and therefore cheaper again.

Oh? 'Stack-type SBCs often have memory provided on plug-cards such as SIMMs and DIMMs. Hard drive circuit boards are also not counted for determining if a computer is an SBC or not for two reasons, firstly because the HDD is regarded as a single block storage unit, and secondly because the SBC may not require a hard drive at all as most can be booted from their network connections'--Wikipedia:Single-board_computer
