[plug] Pi talk

[Jason Nicholls]

If not married to the PI then I'd also suggest looking at 2nd hand mini PCs.

I picked up a Dell Optiplex 9020m i5 4590t with 8GB RAM and 128GB SDD
(internal) for $227. This is a low power unit (idles ~10W) and way more
powerful than a PI with proper full speed GigE and USB3 if you want to hook
up external disks. Nice thing too is you can expand/upgrade it with more
ram or replace the internal disk etc... It's also tiny, about the same size
as my NBN router!

If you consider the cost of a pi4  4GB + power + case, then I think this is
competitive - esp. if you were thinking of getting multiple PIs
