Yes, the mobo is indeed well made. Which brings me to the thing I said back in December that seemed to offend Mr. Time (of Brisbane, QD, if I'm not mistaken) -- put the Sunblade 100 mobo inside a 1-U or 2-U rackmount chassis with the appropriate power supply for 24/7 operations, meaning at least a dual-redundant power supply. The Sunblade 100's power supply looks a wee bit flimsy, but looks can be deceiving. Chances are the power supply is of good quality, but no more than simply adequate for workstation usage. Going to an external enterprise quality hard drive (SCSI or F-C) would help significantly in reducing power supply load. Of course, you will need to add a host adaptor which will take back a few watts. I do not believe you can cluster Sunblade systems. Suncluster only works with higher-end boxes (Enterprise boxes). Besides, if you can afford to purchase very expensive Suncluster licensing, then it makes little sense to be running "cheap" Sunblade systems. Also, in my earlier message, I meant to say UltraSPARC IIe and III, not UltraSPARCIII and IV. The UltraSPARC IV doesn't exist, except maybe in a secret Sun laboratory somewhere.
