!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:

Rules (interactive)

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.

What really separates a PC from a server? Mainly the hardware, but I guess software too. (self.nostupidquestions)

In title, can elaborate if needed.

Edit: thanks everyone, I ended up deciding on an m920q for the server.

Does this media server need to be accessible when you are away from home? Will you store personal data on it?

Out of band management: this is a server feature that lets you access and manage the server even if the OS is down. That's important if you may be away from home and need to fix a boot problem.

You can simulate some of this with PiKVM (remote console access) and PDU solutions (remote power control).

Redundant power: servers often have redundant power supplies, so that if one fails it can still function.

You can simulate this, with short downtime, by having a replacement ready. Mini PCs make this easy by using relatively inexpensive laptop style external power bricks. But also think about the power circuit - is the server on the same breaker/fuse with something that could potentially take the circuit down while you are away?

ECC RAM: this is about data integrity. If there is a failure in non-ECC then a bit flip could cause data corruption.

You can't really get this without ECC. Using a file system that has anti-corruption features can help reduce some of the risk. You probably trust your data to consumer PC hardware, so this would be no different really. It's about risk mitigation.

And that's the main thing here, deciding on the use cases and prioritizing/budgeting how you mitigate risks to each.
