Raspberry Pi fails more often or not when booting is done from MicroSD, booting directly from SSD is better option (enclosure with USPA support better as faster).
I am in process of testing out Odroid M1 8GB ram, paid 162 eur together power supply and metal cover, looks better in real life than in pictures (like iPhone space grey almost).
Max consumption 4,5W max, 44 kWh a year!
Adding 2TB Samsung 970 Evo pro NVMe with 105 eur, 1TB option available with 65 eur (also in Amazon), so total will come 230-270 eur, will sell plug and play starting from 365 eur shipping includes.
It is 4-6x faster than Raspberry Pi 4 Board so for me was a no brainer after looking for an alternative to Raspberry Pi 4 (as mentioned, not available right now or expensive) for myself for months
Have in mind doing faster x86 option also for Umbral Home, little cheaper.
For refurbished, you could find old Mac Mini, specially the Mac Mini late 2014 that lets install NVMe with a special connector under 30 eur.
There are i5 & i7 options available with 8-16GB, stay away from 4GB. They are soldered, can’t change the ram. Earlier 2011 models yes but only SATA SSD.

Feel free to give any feedback. Twitter DM open.
I have an M2 SSD in a usb-3 enclosure. I am testing out if I can boot it on various machines, in which case I have the ultimate in server portability. I can then upgrade to a USB4, whenever those are released.
It has a ubuntu server/full node on one partition, umbrel on another, and linux mint gui with all of it's niceties. It's probably not the most secure setup though, as it isn't encrypted yet. I'm working on figuring out LUKS2.
So far most modern BIOS have had no trouble booting EFI on external drives. If one does, I can convert it back to mbr boot.
