Any good USFF PC's?

Has anyone found a good UltraSmallFormFactor PC suitable for LinuxCNC use? It should have either PCI or PCIe slot. Best I have found is Lenovo uk.pcmag.com/lenovo-thinkcentre-m90p-usf...hinkcentre-m90p-usff

I am currently writing this on a DELL Optiplex 755, USFF with a huge power supply brick attached.
This is the one i use mostly for anything related to .......a lot of things, including running and testing Linuxcnc machines. Have Linux Mint with RT Preempt on it, still has some nice latency times. It was better with Ubuntu 10.04 but not by much, so i am more than happy with it ( especially since i paid 45 Euro for it).
Attached is a latency test i just did for over 40 minutes, while doing all sorts of things on it ( just firefox has over 30 tabs opened with facebook, instagram, this forum, cnczone, ebay, and youtube playing some epic music )

But it does not have PCI or PCIe slot?

No it does not, but there is the same model with a bit bigger case that has PCI and PS in the case, the same hardware just in a bigger package. There are 4 case versions of the same system, i had them all except the biggest, and all work remarkably well. This one has a built in parallel port, that is what i use mostly.

No eBay APP ID and/or Cert ID defined in Kunena configuration

Although that price looks way off south, normally i find them here from 70 -100 euro a piece i very good condition.

Yes but it is not anymore USFF it is SFF. I am looking for USFF with PCI or PCIe....

No eBay APP ID and/or Cert ID defined in Kunena configurationIf you want to use a USFF PC you are probably better off using a Ethernet FPGA card, in which case for used machines these work well:



For new USFF+Ethernet, this one is nice:

as it has dual LAN interfaces

This one also works well:

But has only one LAN interface so if you want internet/localLAN access you would need to add a USB Ethernet /WIFI dongle

(many of the tiny PCs have WIFI built in but they almost always cause latency issues where external USB/WIFI or USB/Ethernet adapters do not)

Yes it seems Lenovo is only one making USFF with PCI slot. That Zotac and Gigabyte ones look very nice ones.

I have one running a machine about the size of that Lenovo. We put it together ourselves with pieces purchased from Newegg.com a few years ago. The motherboard is an intel board with an Atom D2700. It is all passively cooled including the powersuply.
