Question about Acer Aspire GX-781

Greetings Donikrass

I am not the seller, but I think I can answer the question. :)

In such A-brand ready-made PCs, proprietary own-brand mainboards are built in, which you cannot buy individually. They are manufactured either by ECS or Foxconn (in this case 90% Foxconn).
Upgrade options are very limited, the i7-7700 is almost the flagship of the time from Intel, only the slightly higher clocked and overclockable K variant would be an "upgrade". However, overclocking is impossible thanks to the low-end H110 chipset.
A graphics upgrade would also almost certainly require a new, stronger power supply unit, as almost always only the "absolute minimum" is installed.

Generally speaking, ready-made PCs of this kind are not necessarily bad in themselves, the way they come along. But upgrade-friendliness is something else. :)

If you have any further questions, don't hesitate to ask.
