I tried Fulvio's Peruggi keyboard and it works fine on my Apple Keyboard. I made some tests with a PC keyboard by TRUST and it works fine too. I prefer using apple keyboard because I can reset the Mac Mini with the key combination CTRL + APPLE ( on the left side ) + CTRL APPLE ( on the right side ). I tried the same positioned Keys on the PC keyboard and I cannot reset.
So what can you say to me about key resetting? How do you perform it?
