You can use higher end systems such as: * MINISFORUM MS-R1 https://store.minisforum.com/products/minisforum-ms-r1-workstation?variant=47289624690933 * Radxa Orion O6 https://radxa.com/products/orion/o6/ Yes, they are more expensive, but also much more powerful (armv9+ with lots of RAM, etc.) and with a proper EFI boot and a good upstream support. Maybe better to buy one of this higher end system instead of multiple RPi 5? Cheers, Guillaume > > Maybe this situation has changed, and 10 years from now I will be able > to tell.
