There’s a weird bug where you can get four workers per shaft. The ‘hire worker’ button at the end of the shaft disappears after you hire your third worker, but if you click where the button was, you will get a fourth worker for free.
I think you can find it for sale on AliExpress by searching for ‘Topton N100 NAS motherboard.’

Short answer: your power supply should work - you just need the right voltage, current rating, polarity, and connector.
An unregulated power supply is a kind of power supply whose output voltage varies with current draw. In other words, it does not put out a constant voltage - it is only rated to supply a minimum voltage at a certain current draw. In this case, you will need a power supply that can provide 9V DC at 700mA. Because most devices require a constant voltage, you can always use a higher rated supply.
If you test an unregulated power supply with a multimeter, you will likely see the voltage is higher than what is on the label, say 9.5V DC. That is because the multimeter is not putting a heavy load on the power supply. As the current draw increases, the supply voltage will drop. That is why you can use a higher rated device, but not a lower one.
In your post you said it uses a 3.7mm plug, but the manual link says 3.5mm with a positive tip. I assume that it means it uses a 3.5mm phone connector for power, like what you would see on a pair of wired headphones. The important part is that the positive 9V is connected to the tip, and ground on the sleeve. Sometimes, reversing these connections can damage devices, but there is usually a protection circuit inside that prevents this, and I would wager that this is no exception.
Not OP, but looks like the Geekworm KVM-A8. They also make a version using the CM4.
I’ll agree that it looks like watering issues. It could be inconsistent or overwatering leading to cell damage in the leaves, though I wouldn’t rule out root rot or pests since watering issues can invite both. If you are really concerned, you could repot with fresh potting soil and inspect the roots for damage. Wipe the top and bottom of the leaves with a damp paper towel and look for pests just in case.
