Either he had some money available, or he just financed. It's not that hard to get a small business loan/financing for this kind of equipment.

I don't know how many he sold, what his production capacity is, and what margin he makes, but I recon he could definitely make his investments work from the sales of the cases alone. And even if it does not, then there are also future products that this equipment enables. So a good investment if you ask me.
