building a mini itx be like

Budget setup! Third monitor on the left is waiting for a cable. The bigger monitor is a 27'' that i got for 15€, the vertical one I got for free. Mini itx ryzen setup behind the monitors. Chinese mechanical keyboard with outemu blue switches

I'm considering to build a powerful, small/semi-portable mini-ITX PC. Just small box you can easily travel with, kinda like a laptop but a lot cheaper and without a screen, keyboard and battery - I can't really work on laptops anyway (ergonomics!). Stuffed with something like a 4400G when Renoir (mainstream Zen2) comes out, so lots of processing power. Add 32GB+ RAM and one or two SSDs.

I'd say the reason is that I might work from abroad (remotely) next year, but honestly, it just gives me an excuse to break my piggy bank!

What do you think?

Some hardware experts here? Looking to upgrade my PC soon, and would like some opinion on the parts I chose. I'm going for a minimalistic Mini-ITX productivity build, but gaming also.
