I’m looking for suggestions. I have a rack in my office with up to 4U space available. I’m looking to set up a backup and storage solution to try and break free from services such as dropbox & google drive. I’d also love to run a few other things like homeassistant and potentially even Klipper for my 3d printer. I’d also like it to be reasonably quiet if possible.
So what would you recommend? I could get something like a dell poweredge and add HDDs + replace the fans with noctua to keep the noise down or go with a dedicated NAS like synology. Any other recommendations?
Raspberry pi can run homeassistant and nextcloud, but it probably runs better on more powerfull pc. Also having SATA or m2 ports is way better than USB for storage.
Deffo keep klipper on dedicated rpi. You need usb connection with 3d printer and cable cant be too long, it must be quality cable and you should guide it far from motors and other electronics. And not just because of a cable, it make sense to have a dedicated sbc for a machine that runs 5-50 h long jobs.
I went for DIY PC (cheap/silent/flexible) server and rpi4 for klipper. 1GB ram should be enough (I have 2GB) for klipper and you can keep your rpi inside of printer enclosure. I have mine with no fans and enclosure goes up to 40 C, no problems so far. There are also cheaper boards simmilar to rpi, but I have no experience with them.
HomeAssistant will easily run on a Pi, it’s Nextcloud that needs more horsepower.
