Given that, the evaluation platform (at least the one I had) was shipped in a horizontal 1/2 height Antec desktop case with retro styling and colours, despite the fact the docs explicitly stated that the HPC II is not a desktop machine (noting it had no gfx or legacy PC I/O support). Historic trivia aside, this was the 1st introduction of the e600 procfam as an evolution from the earlier G4. However even with the claim to being "1st e600" it seems the 2005+ era was turning its attention to multicore support and from my memory this poor guy was quickly overshadowed by the dual core MPC8641D.
