Any opinion on whether commercial single board computers are genuinely more reliable than consumer systems from the 486/Socket 7 era?

I've picked up a handful for 486 sbcs, some Slot 1 and Socket 370 sbc and they've all worked really well. There are some obvious tradeoffs, like no AGP slots and sometimes missing level 2 cache on 486 boards, but in general they are highly configurable and documentation tends to be top-notch. My vintage computing target is really early to mid MS-DOS gaming, and a few late 90's to very early 2000's Windows games, so Pentium III 600mhz and 5x86/133 are right up that alley.

The cards generally have far fewer electrolytic caps (none on most of the 486 boards) and none of those godd@mn barrel battery suicide machines. They report higher max operating temperatures/humidity/etc. on their spec sheets.

Superficially I feel like these should be more reliable long-term than a lot of the consumer motherboards.

Anyone have experience or input on this subject?
