Apple Mac G4 Cube and T2/Linux
The Apple Power Mac G4 Cube was a quiet, fanless, compact Macintosh personal computer from Apple Inc. and was sold from 2000 to 2001.
This 9 3/4 x 7 3/4 x 7 3/4" (24.8 x 19.7 x 19.7 cm) cube of "polycarbonate plastic and other materials", houses a PowerPC G4 processor and won several design prizes and was included in the permanent collection of New York City's Museum of Modern Art ...
Notes
Unlike on other Apple systems of that time, suspend to RAM does not yet work under Linux out of the box, due to lacking re-initialization code for the ATi Rage chip (Linux r128 FB driver). When updated with a Radeon based card with proper re-initialization code in the Linux kernel suspend to RAM just works as usual.
