!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

It's probably fine, but you can accidentally short it when moving it around by touching it or resting it up on something conductive, even if you're careful dust might short it as well, but this is much rarer.
As a general rule I would try to avoid it, but would not be my first concern.
It does can but maybe no?
In all seriousness, its gonna depend. If it can survive minimal ventilation, throw a shoebox with some holes at it. You probably dont want it getting touched, but so long as its not, you're prolly fine.
No, it will be fine. It doesn't need a case.
I killed 3 Raspberry Pis by putting them onto a metal surface while turned on (first two times I didn’t know what was happening and the third time was accidental). Do not recommend.
In college (2003ish), I ran a desktop PC without a case. Hell I ran the processor (450MHz P3) without a fan, just a passive heatsink. It ran fine.

They still make passive heatsinks that work for modern CPUs, but they're fuckin massive and not incredibly effective compared to just.. putting a quiet fan on it.
For a Pi? Probably not.
For a desktop PC? In most cases the board needs the case to manage proper airflow for cooling. Running bare could make it overheat.
Most cases have ridiculous nonsense for cooling though. Laptops usually have considerable thermal engineering, but kinda set the threshold of real hardware requirements.
I was just given an old "gaming rig" someone didn't want that had water cooling, 9 fans, a cobweb of LED wiring, and the most obese ABS panels attached to the sheet metal case.... The thing works fine even when overclocked with no fans except the one built into the power supply and GPU. Only the one in the GPU cycles on enough to be audible... This guy had a freaking harrier jet taking off in the room beside him for a decade.
I wouldn't worry about it unless you have animals around. Mostly to protect from fur
If you are statically charged and you touch the bare PCB, you will do damage. Having a case prevents you from touching the PCB directly and a metal grounded case will also allow you to discharge without damage.
You might do damage. Though that is very hard to actually do and quite rare in practice.
I've never had an issue, but I've been careful with placement and handling.
How about a cardboard case?
