I was aware of a few options out there, but I was very fortunately introduced to one spectacular little box...the Intel NUC!
The unboxing experience is nothing short of pure marketing genius!
The physical form factor of all models is identical:
- 4.6" x 4.4" x 1.6"
- 11.7cm x 11.2cm x 4.1cm
There are 3 different processor options:
And there are three different peripheral setups:
- HDMI 1.4a (x2) + USB 2.0 (x3) + Gigabit ethernet
- HDMI 1.4a (x1) + Thunderbolt supporting DisplayPort 1.1a (x1) + USB 2.0 (x3)
- HDMI 1.4a (x1) + Mini DisplayPort 1.1a (x2) + USB 2.0 (x2); USB 3.0 (x1)
On the left, you can now see a 24GB mSATA SSD, and beneath it (not visible) is an Intel Centrino Advanced-N 6235 WiFi adapter. On the right, I have two 8GB DDR3 memory modules.
Note, to get wireless working properly I did have to:
echo "options iwlwifi 11n_disable=1" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
The BIOS is really super fancy :-) There's a mouse and everything. I made a few minor tweaks, to the boot order, assigned 512MB of memory to the display adapter, and configured it to power itself back on at any power loss.
Speaking of power, it sustains about 10 watts of power, at idle, which costs me about $11/year in electricity.
Some of you might be interested in some rough disk IO statistics...
kirkland@living:~⟫ sudo hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 11306 MB in 2.00 seconds = 5657.65 MB/sec Timing buffered disk reads: 1478 MB in 3.00 seconds = 492.32 MB/sec
And the lshw output...

It also supports: virtualization technology, S3/S4/S5 sleep states, Wake-on-LAN, and PXE boot. Sadly, it does not support IPMI :-(
Finally, it's worth noting that I bought the model with the i3 for a specific purpose... These three machines all have full virtualization capabilities (KVM). Which means these little boxes, with their dual-core hyper-threaded CPUs and 16GB of RAM are about to become Nova compute nodes in my local OpenStack cluster ;-) That will be a separate blog post ;-)
