Righto :)

I was thinking of usb3 hard drives. No need for internal storage if using spinning rust.

On older laptops with optical drives you can sometimes replace the drive with a sata tray and add a second drive that way.

But yes, a server that looks like a server and can recover after power loss is useful.

A cheap laptop might also be worth considering? Built in UPS that way, and sometimes UPSes have a large standby power usage. Would support a couple of bus powered drives as well.

Main drawback is no recovery if the battery drains fully.
