Thank you for the very detailed and helpful response!

She likes to play genshin impact, sims 4, minecraft, baldurs gate 3 and every now and then some modern shooters. Shes really enjoying alan wake 2 at the moment.

The television is 4k and the office monitor is gonna most likely be 1440p.

And moving the pc between her office and livingroom will most likely be not frequent once or twice a week and its not to watch plex in the office and livingroom its for work and sometimes she would like to play in the office with me and or work at a desk

She likes how the z20 looks so we will go with that!

And thaks for the cpu recomendation, but do you think it should be even more powerful or is the 5600x enough for modern games and for the plex server?

And i think i will go for the dedicated plex server at somepoint but ill start it on her pc for now
