For less than 100 USD ($90 - I just checked) there are several well-reviewed 2230 form factor 1 TB NVME drives on Amazon - specifically, the Corsair MP600 Mini, the Teamgroup MP44S, and the Inland TN446. And though I don’t have one of those drives (I have the 2 TB version of the Sabrent Rocket instead) I speak from experience when I say that the install process is straightforward.
If they have dedicated servers per region that handle payment processing, and they would need to be upgraded in order to be compatible with currently supported OSes, yes. Or if just maintenance costs for keeping them online are high enough.
Or if they have to pay an annual fee to continue selling (but not distributing) the games.
Or if the annual base costs for the payment provider exceed their revenue.
