Nope - still don't see the reason why a toy miner requires a pre-order of months.
It's old mining chips with poor Hash/Joule.

I'd just wish sidehack would make something with recent mining chips.
All the manufacturers are ignoring home mining, expecting 3kW and more per miner, so we end up with poor performance old hardware for home miners.

125 watts 2TH/S is 62.5W/TH ... = over 810W for 13TH/s ... if you wanna compare it to VERY OLD hardware.
(and that's assuming they're not doing the typical over hype stats also)

The node option is pretty poor also.
Firstly, there's no way you'd ever run your own solo mining with it, that would just be a major block loss waiting to happen for most people.

So to run a node yourself, you want an at least an i3 with at least 8GB ram and 1TB HDD, stick Ubuntu on it and add Bitcoin core.
A current full node needs over 360GB of disk space just for bitcoin.
500GB isn't expecting it to last for very long.

NVMe is faster than HDD, but makes no difference for the bitcoin network at all.
Space matters.

Bottom line is it says $600 for old technology and a poor spec node that will need upgrading in the not too distant future.
