Odroid H2

Sorry Blazini, i was thinking about used enterprise edition Dell and HP, i can get them for cheap in perfect condition and they never fail, core i5 for 70 to 80 euro.
I do get the point you're trying to make and the reasoning behind it, NUC is also very expencive for what it offers, and new computers at reasonable prices are not any good.

Exactly.

My one absolute requirement is that I can run the PC off of the DC power supply,

I had a J1900 Industrial PC on this machine in the beginning, which is fine for a mill or anything really, had 2 1gb ethernet ports and a bunch of serial ports and it just took 12v on a barrel connector. I use machine vision cameras and when they would start to display the processor would get hit hard and the latency would spike.

The I built a ITX with an HDplex DC-DC power supply and an AMD A10 9800k. No problems with that other than it's a 95w CPU in a small case so I had to use full copper server blower cooler that sounded like an airplane when the cameras came on.

Surprisingly enough this seems plenty strong for my machine with the camera's and that machine is not a large machine so the smaller the better as long as it can handle the cameras. The J1900 got sent to my Mill which it does absolutely fine running the commutation on a brushless spindle motor with a 7i96 and I'll build something more suitable with the A10 board.

I would have bought the Odroid H2 anyway, I'm on a kick to stuff as many small computers albeit ARM, or x86 in just about everything. I know you can pickup used hardware dirt cheap, I can build about 8 systems as it is myself with all the PC hardware I have in the closet, but that wasn't really the point. There's certainly nothing wrong with using old hardware, I just didn't expect the replies about using older stuff when I posted this. The fact that you can use old hardware is a give in, but looking for something new it's pretty hard to beat this little board. I VNC into the machine almost exclusively for dev work so the fact that it has 2 NICs onboard is pretty convenient so I don't have to bother with a dongle since otherwise the onboard NIC is dedicated to the Mesa eth board.

NICE
CAN you make a quick tutorial on how you did it in a NEW tread so people can get this redone
by there own on the now given software maybe

Reproducing somthing is offen more complicated that a new setup

im With you as you DID it and someone shoudt have done it to prove
YOU DID Well

It doesn't really need a tutorial like an ARM board or something that's difficult, it's a normal X86.

I usually compile a new RT patched kernel, but I was having issues getting the normal GCC compiler to work, my environment was stuck using the Linaro ARM compiler for some reason.

Tommylight's post with the kernal deb is all I wound up doing for this ATM

what is the perrifery
HDMI ssd usb DVD or remote setup via ETH

Not really sure what you're asking here.

1)Buy the board, and a 15v power supply
2)Get an NVME SSD, a SATA SSD, a SATA HDD, or an Odroid eMMC chip for storage, any one will do.
3)Get a stick of DDR4 laptop memory
3)Put Linux on a USB stick
4)plug in HDMI or Displayport monitor
5)install linux from USB stick to whatever drive you picked up in step #2
6) install kernel as per tommylight:
simosnet.com/debian/packages/Konalinux/debian/kernel/
linux-headers-4.16.12-rt5-kona-rt_amd64.deb
7)plug in Mesa ETH board to either ethernet port of Odroid H2
8)do whatever you usually do

Sorry to be so obtuse, but I really don't know what you're asking. Board specs are in the link in my original post.
