Power Series
From TechPubs Wiki
The PowerSeries systems are the first multiprocessor computers made by Silicon Graphics and were typically shipped in a single or twin tower case. PowerSeries systems were first produced in twin tower shaped chassis, and later on single tower chassis was introduced. The high-end systems (more than 4 CPUs) were shipped in a "refrigerator-style" rack due to space limitations in the desk-side cases.
Some resemble the earlier Professional IRIS systems.
