A:AnswerWhat a crappy response from asus. Yes, you can upgrade in fact the first thing I did was swap out the cheap motherboard and power supply with a decent set. Gigabyte aorus ice x870 with 4 come slots and much better board by far. For this much money they should have at a minimum used tuf gaming not cheap prime. I replaced power supply with a 1000 watt gold supply. Nvme with 4 drives of 4 terabyte each . Gen 5 for the os and gen 4 for the rest .
