Does a fanless mini-ITX like this still require case fans, or is there some way to have a case without fans, possibly with convection cooling?

You could always try and figure out what Calyos is doing in their prototypes.

Not exactly an easy solution, but its definitely possible if you can take a massive heat sink and tie it to each component.
They have some information relating to this on their site, but its again really only theoretical. Linus Tech Tips got a chance to review a prototype version in person.

Totally different. My objective is to avoid all that heat piping stuff. I'm asking about the type of board I linked that has its own heatsink already on the CPU. I'm wondering if that could be cooled with convection internally inside the case, not with external heatsinks.

It works if the case allow for some natural convection. Just a sealed box and weeks of Prime95 is a recipe for disaster. ;) The Celeron J3355 has a TDP of 10W.

if your CPU consumes low enough power, absolutely it's possible.

Probably you'd want a vented case to permit fresh air to flow in via convection.

If your case is sealed, then you have much less tolerance.

The only way to know the limits of a custom system is to build it, stress it, and see what happens. With today's apps now allowing throttling based on temperature, i'd say it's safe to experiment.

Any case you can find with the most ventilation holes will give you the best cooling performance. But depending on your tastes, you might trade off the aesthetics.

Theoretically you could just attach the hardware to a piece of plywood and leave it fully exposed, which is maximum cooling efficiency but doesn't do much from protecting it from dropped paperclips & your cat leaning against your memory chips

Thanks. I would probably try to achieve good ventilation without allowing too much dust to settle into the chassis if possible.
