That seems >hard to believe. The mail server is easy. Nextcloud is porky. The easy answer is to get a cheap PC but you decided you didn't want to do that. And you don't want to spend any money. That leaves you in the uncomfortable quadrant of "unreliably available specialized boards built from ARM components". It can be done but it will take more work to identify and acquire the board. If you don't like that, then you can change one of your other parameters (software, writing off x86, price, etc) and then the problem becomes easier with more options.

Bad data in memory is bad enough, but bad data written to disk is the gift that keeps on giving -- replication overwriting good data, snapshot and backup rotation overwriting good data, archive destruction destroying good data, etc.. The longer it takes to figure out the data is bad, the less likely you can recover. For me, the key points in favor of ECC are: 1. Wikipedia gives DRAM bit error rates (BER) from 10E-10 to 10E-17 errors per bit per hour [1]. So, 1 error per year for 114 kB to 1.14 TB of DRAM on average under some test conditions. 2. In the wild, not all chips, modules, sockets, capacitors, motherboards, etc., are healthy or compatible. Real BER's can be much higher. 3. The BER of DRAM tends to increase as the transistors, capacitors, lines, etc., get smaller and faster [2]. Given Moore's Law, manufacturers must be hard pressed just to maintain the BER with each new generation. 4. Moore's Law again: the amount of DRAM in devices has been increasing exponentially, thus adding more DRAM that can error. So, it is just a matter of time before the error probability curve crosses the BER specification. One article I read said desktops and laptops already crossed it at 8 to 16 GB. COTS servers can have one or two orders of magnitude more memory. David [1] https://en.wikipedia.org/wiki/Dynamic_random-access_memory [2] https://danluu.com/why-ecc/
