I am a bit behind a schedule with my work after all this hardware
switches so no time for play really at this point. But I got ASUS TUF
Z890 PRO WIFI motherboard with some free PCI-E slots even with onboard
UART do I plan to attach serial console output for verbose / debug on
some old android tablet in a free moment :-)

By the way all this new brave-new-world hardware is so nice - there is
no pc speaker anymore (hey I used that!!), there are advertised
Thunderbolt/USB ports and 20Gb USB4 ports but turned out to be only
onboard connectors with no panels or even adapters included with the
bundle and I cannot find them spare anywhere, also one of two PCI-Ex1
slot is located right under PCI-Ex16 so its covered by the GPU - all
looks so good on paper :D

Ugh :-( I only have some small old NVIDIA.. gave away all old setup
with AMD RADEON RX580 after if was crashing whole system all the
time.. there is onboard Intel but I am sure it will not even start..
and AGP/PCI/ISA cards does not count here :D
