First off, a good computer. An i5-8400 handles very well against last generation’s i7-7700 for example. But this literally cannot be upgradable to a good gpu. Why? Because there is a big, massive disk bay in the way that makes it impossible to disconnect the psu from the motherboard.It’s a 300 watt psu btw. Any card above maybe a 1050ti or requires psu power is not gonna be an option. You’d have to saw the disk bay to replace the psu. A warning to all gamers, build your own or if you want an upgradable pc, stay away.
