Well, I suppose that more or less answers the lingering worries. Thanks for the links and the test results!

I guess I'll quit fretting over the DE10-Nano and go back to my usual routine, fretting over the longevity of my CRTs.

That you have all the reason in the world to be worry about, especially since those bad boys can say "goodbye" in so many ways

Heh heh, yeah two CRTs die on me every year. I have 9 left now, but I'll need to go buy some more.

My MiSTer FPGA has seen nearly daily use for two years now. No probs. Use a compressor to clean it from dust.

Intel have tested the Cyclone V for 2.1 million hours, with zero failures.

Spread across many devices maybe. but not one device cumulative time, because I don't believe the DE10 nano has been in production for 239 years yet, which is approximately how long 2.1 million hours is

That said if it is using SRAM, it isn't subject to read/write cycles in the way NAND is.

The Commodore VIC-20 used SRAM. Some of those are still humming along just fine.

If you have the standard hardware stack inside the metal case with the analog I/O board and use the VGA port, most of the mechanical port failures should be prevented since only power and USB bridge would be connected, and those connections are pretty permanent. Also the metal case should act as a Faraday cage when it comes to ESD risk. I guess the only other potential risk could be due to overheating and SBC solder failure, if the fan fails and you run the MiSTer under heavy load continuously in an environment with no airflow. I guess, if you stop hearing the fan and you don't have a good heatsink attacked to the DE10-nano's chip, you should at least check and replace that fan...
