[App_rpt-users] Pics/details of the 12VDC mini PC I have running at W3RWN

[Randy Neals]

I've built a new Mini-PC for my re-worked W3RWN node.
Thanks to those on list that let me know about their experiences with this
Motherboard a week or so ago.
thought I share a bit about what I've done, and perhaps others benefit.

Pictures are here:

This is an entirely 12VDC powered motherboard, with a newer SSD technology
called MSATA which results in the SSD being a module on the motherboard.
This is very neat because there are no inverters, or additional power
supplies needed to run this PC from the same 12 VDC power supply as the
repeater.

I was concerned that a Dual Core Atom might not be enough, but it seems to
work just fine for my node using a URI to control a 70cm repeater.
I installed ACID_CENTOS, and it installed clean with no futzing around. No
asterisk reboot cycles, all clean.
Running TOP shows Asterisk taking about 10% to 12% of the CPU, and minimal
other load on the system.

50mm x 10mm Fan installed in Habey case with variable speed from
motherboard fan header. Set for 10% to 100% fan range in BIOS. (Got the fan
from Amazon)
17mm x 17mm adhesive heat sink - Digikey ATS-52170G-C2-RO stuck this on the
Intel PCH chip (Northbridge) which was very hot to the touch.
(Thanks to the folks on list who suggested I look at the PCH temp to ensure
long life)
