Well as you all know IRIS is the default, and, apart from it being a flower, it also sounds like an Egyptian God (Isis, the mother God), I decided to keep the Egyptian God theme going.
The O2 was my original system, so it retains the name IRIS.
The second O2 I bought to replace it (long story), is named Osiris.
The Octane (when I get it up and running) will be named Anubis.
Don't ask me why, I don't even know myself, but for now, that's where it stands, till I get bored and change everything again.
Man is the only animal smart enough to build the Empire State Building, and the only one stupid enough to jump off it.
