I wouldn't assume that without taking a look, and not just at the case,
but at what software reports it to be.

I don't know how much I trust that page, because it categorizes computers
by their software instead of by their hardware. The link to the modem
updater says that it installs firmware 2.2, not 2.3, and there is no
download because it was superseded by updater 2.0, mentioned for later
iMacs, which installs 2.3 firmware. The iMac firmware 1.2 is only for the
tray-loading models, not the slot-loading ones, which need 4.1.9 firmware.
As for the drive update, I would install it, then check what firmware
version it installed, and compare it against cdfreaks.com and rpc1.org

That actually doesn't say much, and hardware matters more than software in
most cases anyway.

AFAIK, Ubuntu cannot netboot because the installation kernel plus initrd
exceeds the size of the bootloader's TFTP buffer. However, that would in
no way prevent a net-install.

Oh, I'm sure the live image can wait until next month's release.

...and I suppose Microsoft Word will?
