John,
I always use a separate 120 VAC input power brick. I don't like
sharing power supplies with the PC. If you get a relay on there and
get kickback you can degrade your PC power supply. Not worth the risk.

I have never had a power brick from these guys fail.... yet. And I have
purchased a lot of them.
If you want to make a bullet proof setup, get a Samsung SSD 850 EVO drive.

The life of those things is suppose to be a decade or more even with
frequent writes.
They aren't dirt cheap, but if you want to do it once, close the control
panel and then run the machine for 10 years, it is likely well worth the
few extra $.

Thanks Martin,
Where are you sourcing the 12V for your supply. From the CNC power supply or a
separate adaptor?
It looks like, from their web site that this supply could handle up to 24V in.
That would work well with the control power supply for relays etc. on my
system. Or just the raw 16V that comes from the transformer.
Very cool site. Thank you.
John

John,
If it's any help, this is what's running mine:
Motherboard

J1900 Celeron
Drive
http://www.newegg.com/Product/Product.aspx?Item=N82E16820721106
Case
http://www.mini-box.com/M350-universal-mini-itx-enclosure
Power Supply
http://www.mini-box.com/picoPSU-90
RAM
http://www.amazon.com/Kingston-ValueRAM-1333MHz-Non-ECC-
Desktop/dp/B002K23V1Q
(I think all those links should work)
Motherboard/CPU combo is very low power and offers a parallel port for
simple setup. I use the onboard graphics.
Martin

Hi Dave,
Thanks for the info. I didn't realize that Umbuntu 12 LTS ran LinuxCNC directly
connected to a mill,router or lathe. Good to know.
What model PICO supply? The ones I googled appear to be very low power.

I don't think you are saving time or money using old hardware.
What about this??? $70.
The J1900 CPUs are known to work well with LinuxCNC.
If you search the list I think you will see several references to them.

I have a server running a J1900 with Ubuntu 12 LTS and it installed with
zero issues.? Its been running for a few years now.
There is a reason why old PCs go cheap..
I would use a Pico power supply with it and a small SSD. ? I have found
the PICO power supplies (the real ones, not the clones)? to be more
reliable than conventional power supplies.
I can get 2-3 years out of conventional power supplies when run 24x7,
but I have yet to have a failure with a Pico and I have installed
several over the last 5+ years.?? I don't know why.

But it looks like back in 2009 there wasn't a lot of support from NVidia for
this board. I wonder why it works so well with Knoppix?
I'd had to swap my multihead Nvidia card to an AMD based one to get
things working with OpenSUSE ... Still problems getting a reliable cross
screen desktop, but seems to be better support on SUSE for the AMD based
cards. When a recent update wiped the setup, help from the suse forum
gave a boot fix to restore operation. As I said, the days of VGA cards
that just worked even on multiscreen is long gone :(
