I miss Sun hardware, especially in the sun4c era. Everything was so solidly built and well thought out compared to a lot of PC hardware. The IPC/IPX is still one of my favorite form factors.
Still a very cool form factor, though nowadays beware that the PSU is a cap goop timebomb:

I greatly enjoy the Sun3 and Sun4c/Sun4m era, always under SunOS 4. Probably because that's what I started on with my first UNIX account (Grex). Probably why I still prefer the BSD-style distros nowadays.
