>From here, and I'm running a linuxcnc buildbot on my 2gig 4b, all it needs is adequate cooling, in my case the 4 little bitty heat sinks AND a stolen 12 volt video card fan running on 5 volts blowing rather leasurely on them. And it runs from power outage to power outage, which I have to create by shutting off the power strip its running on as I have a standby that starts in about 4 seconds, and its on a 650 WA UPS with a 2 minute shutdown I can't change. It just works. For months and months. > You'd probably want to use USB-Ethernet adaptors. You could have more > or less as many as you like.
