Hello guys, first of all sorry if it's the wrong section but I have multiple questions and I wasn't sure where to post, I can make individual threads if it's better.
I'm planning on buying a Raspberry Pi 4 4GB and relative accessories taking advantage of the Chinese 11-11 and Amazon's Black Friday (and maybe Melopero, the official Italian Raspberry reseller). My goal is to use a single board for multiple purposes:
-a media server using Plex or Kodi, for content at 1080p at 60Hz or less without transcoding, to 1 or 2 clients at a time
-a basic NAS for personal use, at least on the beggining just for the local network
-a home automation hub with something like hass.io and a radio module (RFM69) for the MySensors project
-a Pi Hole DNS sinkhole
I have a some questions:
- Is it possible to run all this things on the same Pi or the performance won't be enough? I can sacrifice something and maybe get another Pi in the future.
- Can I use Raspbian with docker containers if needed or should I expect conflicts or other limitations? I wanted to boot from a flash drive but I read that it's not possible on the Pi 4 yet but I would at least move /root on a flash drive faster than the sd.
- How should I handle power?
Let me explain this last one. I intend to fit the whole project inside an ITX case using adapter plates (that I would build), I have found a used Coolermaster Elite 130 for cheap in a local site but I am waiting to solve the power supply issue before buying. I have a 2.5" drive and a sata to usb cable and I plan to add more drives down the line so I was thinking of putting an active USB hub inside the case. For the cooling I plan to use a passive heatsink and the case fans, they're 12V but they're big enough that at 5V the airflow should suffice. So the options are:
-the official power supply and a separate power supply for the hub but then I would have to manage 220V AC inside the case and a mess of sockets and wires, the fans would be at 5V and I could not use 3.5" drives
-a 5V power supply of those that are used for led strips (somehting like this https://www.amazon.it/dp/B07DQKM9P7/) but they're not very reliable and I don't know how I could stabilize it, like before the fans would be at 5V and I could not use 3.5" drives
-a 12V power supply similar to the previous one and a buck converter, I would lose in efficiency but the buck converter should stabilize the output of the power supply, I would run the fans via a PWM controller and I could use 3.5" drives if I wanted to
-an ATX power supply, not very efficient and I'm not sure how reliable, I have a couple of old ones that work well but they're old and cheap and not even rated
-something that I havent thought of yet
I haven't settled on any specific model for the hub because I want to choose the power supply configuration first but I've read that some may have issues of backfeed, there are lists of known good models but the're quite outdated, should I worry or any decently built hub would work?
I am not a complete beginner with Linux or electronics but I'm no expert and I have never had a Raspberry Pi so I chose to post in the beginner section, I'm not so sure about it now but I'm also new to the forum so tell me if I made the wrong decision.
Thank you for reading this far, If I made mistakes please correct me, I'm here to learn. Any help is appreciated.
