@Kronos Sure, maybe not bullet proof but darn close!
All the PowerMac users I talk to that own a business and used the platform, all used the PCIe single processor system. The dual 2.5's had a high failure rate and the PCIX stuff did fail more as well. The single processor PCIe stuff is the best from that era, that we luck out to use with MorphOS. As a bonus it is the fastest...
The heatsink alone is a work of art :).
If new hardware were to show up one day, I wouldn't be upset :)
