The iBook G3/366 Special Edition (SE) shares the same Apple model number as the original “clamshell” iBook, but has a few upgraded internal specifications. The iBook SE increased the processor power to 366 MHz and shipped with 64 MB of RAM and a 6.0 GB hard drive.
The SE was also offered in a more conservative case color that Apple referred to as “graphite and ice.”
