I managed to get an SSD to work on my MicroA1, though if I recall correctly I had to considerably drop the speed in order for it to work.
A PCI graphics card into my MicroA1 - It is but a dream. To be honest, I even tried to put a USB-2 Card into it, but that didn't work. - You are stuck at the snails pace of USB1 standard. Ugh!
Overall, the MicroA1 is the Amiga equivalent of a Fiat Multipla
