I would install a graphics card in my PC just for the occasional game, except it would ruin the whole concept of a completely #silentPC with zero moving parts. #0dBA #fanless
Even if I could managed to get a #PassivelyCooled graphics card, it would block the airflow, because it sticks out 90 deg from the motherboard. My open air case does have a card cage to twist it 90 degrees that I can install, but still.
Might need a new PSU, too. Mine is only 500 W (Seasonic Prime TX-500 Fanless)
