They have 400k of stock, though. It's common for a company not to keep a lot of cash around and borrow as needed against stock, which I would guess they are doing as they have 200k+ of creditors.

So, my guess is that they used income to build up stock of their clevo lines in order to reduce delivery times and increase their market to delivery sensitive customers, and now they are leveraging that to invest in the custom versions. If they are doing their own sw and there product is an integration of off the shelf parts, maybe it's doable.
