You may have made your selection already but if you are looking for an
already boxed up PC solution and do not need the expansion card element for
it (like special plug in interfaces apart from USB or Ethernet) then you may
find the Intel NUC or Gigabyte Brix solutions useful. Just been playing
around with each in creating myself a decent CAD-Station. Small, Fanless and
all you add is the DDR3 Memory and SSD to give you the full solution.

Not fanless, and not sub 5 Watts. What a stupid requisite,
considering the application.

Straight HTPC, sure, but all this talk about expansion, etc.

This PC is NOT sub 5W, NOT fanless, but IS a real computer and IS the
type and class of machine needed for this application.

I have a few.

I also have a 4 watt fanless Cubox-i4Pro, ARM CPU based machine.

This person seems to want a machine that does what a specific, single
use solution provides, but wants some kind of regular PC utilization
from it. Adding things not already incorporated typically uses more
power than the pre-integrated solution will.

So, the more you get on the thing at buy time, the less you will have
to add, and the better it *should be* integrated into the device.

Acer and Asus make good machines.

From what I could tell, the Intel NUC was a good concept and idea, but
made the mistake of using USB 2.0 and other, older feature choices which
made the entire line a no-go for me. They MIGHT be able to catch up
with hard tech type consumer demands, if that is even in their goal
playbook. They may have written them off as a failure, but I do not
know how well they sold.

Americans (all consumers in general) are completely uninformed about
true product quality and efficacy these days. Even the consumer rags do
not keep up.

It needs to have the heating and cooling arranged so that it gives a push at all times. Longer tubes do help as well as bigger diameter tubes.

I'm talking about getting it started. Just like an induction motor has
a small number of coils which give the initial push to a stationary
rotor, the heat source and cold source need to be a little offset so one
chimney fills with the warm fluid and the other fills with the cold
fluid. Otherwise it may not start up. But once in motion the hot and
cold fluid will obviously follow the flow and continue the siphon.

As long as the hot pipe goes up at the start, and more than it does down, it will start.

Until the flow has started, which pipe is the hot pipe?

The one headed up from the heat source. Density change starts the flow.

Ok, I see. One pipe is "up" from the heat source and the other pipe is
"down" from the cold sink. So how does the unit tell which I intended
to be up and which is down?

The up pipe is top on both heat exchangers.

Ok, there is our asymmetry. In effect the heat source is at the bottom
of one pipe and the cold sink is at the top of the other pipe. See my
post at the top of the quotes. We have come full circle.

Agreed the Intel NUC DN2820FYKH is not sub 5W (power stated as 36W but it
seems that may include a margin for the additional bits you add to the
barebones). It seems, though, to be totally fanless. I am using the SanDisk
256Gb SSD (6GB/s) and have 8Gb of DDR3 RAM fitted. Datasheet for my NUC is
<http://www.intel.co.uk/content/dam/www/public/us/en/documents/product-briefs/nuc-kit-dn2820fykh-brief.pdf>.

I also have two Gigabyte Brixs GB-BXCEH-2955
<http://www.gigabyte.us/products/product-page.aspx?pid=4860#ov> each with
8Gb of DDR3 RAM and 256Gb SanDisk SSD. This also seems to be fanless.

When I say that these PC's seem to be fanless, short of hooking out the
board to look closely underneath it, there has been no fan sound from the
units that have all been running continuously for the past 100 hours or so
without raising their temperature much. So, if they have fans they are
extremely quiet (it was not on my list of requirements for purchase that
they be fanless).

I went back to read the original post on this and the OP seems to have not
clearly stated what he was really after except for the PC functionality and
that the solution is fanless and sub 5W. I am not sure the 5W limit would
yield any useful speed of PC functionality. The OP was also not clear
whether or not he needed expansion facilities or not. I just suggested that
the NUC and Gigabyte Brix solutions, although seemingly busting his power
limit, might have been worth the consideration.

So, the more you get on the thing at buy time, the less you will have
to add, and the better it *should be* integrated into the device.

Interesting machines but I noted the dollar prices. My boxes, even when I
installed the RAM and SSD units still cost me less than ÂŁ250 each. I am
using two for building up a multi-screen CAD Station with a back-up server.
The third box was for a contracted task that required me to run a real
Windows 7 machine (usually I am all Linux).

I got one for "free" as they were part of the swag at a recent trade
show (also a Samsung Gear 2 watch) that cost $50. This is not something
to use for gaming.

The normal price is around $150 but that's without memory or storage.

5W TDP processor, nice. I was waiting for this one to hit in Australia,
seems suppliers are running out the predecessor model.

The normal price is around $150 but that's without memory or storage.

I ended up buying a Mini-ITX Gigabyte GA-J1900N-3V MoBo for AU$125,
add memory, hard drive and case, still a good buy.

More info on measured power use in another post soon.

http://www.intel.co.uk/content/dam/www/public/us/en/documents/product-briefs/nuc-kit-dn2820fykh-brief.pdf>.

I nearly bought this small Intel NUC you mention, the 36W is the 12V @ 3A
power supply for the thing, the NUC power consumption.

I ended up with a Gigabyte GA-J1900N-D3V, which has a 10W fanless Intel
J1900 Celeron Quad Core 2GHz (2.4GHz boost) CPU, I added 2 x 2 GB DDR3L
memory, and a small 2.5" hard drive. All that runs off a 12V @ 4A power
supply via a 12V DC to 24pin ATX power converter.

Photos here: <http://bugsplatter.id.au/system/d3v.html>

I'll hope to buy a case for it this coming week.

This little PC is intended for 24/7 operation as my Internet facing box.
What decided me was the MoBo having two Ethernet ports, perfect for
firewall duty where one goes the (bridged) modem, the other to
localnet.

Power usage from 12V to DC-DC converter is measured at around 1.4A
(+/- 50mA moving around) on CPU intensive task (compile linux kernel:
'make clean; make -j5') and around 1.02A (steady) idle.

Connected are one Ethernet port, one VGA monitor, ps/2 mouse & keyboard.

I've yet to get the CPU to idle down to proper low power idle, the
kernel is a bit slow to catch up with new hardware. I may have to
dabble with cpu-freq code.

All up cost will be around AU$332:
- $125 Gigabyte GA-J1900N-D3V Motherboard (now $119)
- $50 2 x 2GB DDR3L SODIMM memory
- $62 WD Black 320GB, WD3200BEKX
- $95 Antec ISK 110 VESA Mini-ITX Case with 90W Adapter

Still deciding if I'll put in a small SSD to let the hard drive spin
down.

I'll probably use the 12V adapter the thing is running on now, rather
than the 90W power supply the case comes with.
