Using a computer without a GUI, i.e., nographics, is standard practice when using networked computers. A majority of computers today are connected to networks

This nographics computer is called a "router"

This computer may only be used for limited purposes, hence the names. But its use is standard

A "router" can be used as a nographics "general purpose computer", i.e., it can be used for more than just routing packets

A "general purpose computer", graphics or nographics, can also be used as a "router", e.g., by enabling packet forwarding in the kernel

Using a PC without a GUI is pretty non standard so that's one reason. You mentioned you only used VGA text mode, but what did you actually use it for? What apps did you use etc etc.
