What’s great about Mac minis is that they’re extremely power efficient since they’re ARM machines, so if you live somewhere like in Europe where power is expensive, it can save you a lot of money. They’re usually completely silent too.
Depending on their needs, I’d suggest OP to get a used M1 Mac mini, they’re great value for money.
I’m no lab scientist but when I switched from a hackintosh to an M1 Mac mini a few years ago, my total electricity consumption went down by around 15-20%. This can mean a lot on the long run if you’re tight on budget.
