This is obsidian, an IBM RS/6000 43P Model 150 built in Rochester, Minnesota, in June 2003. We acquired this system in September 2021 with minimal provenance, and it still serves us (as well as this page) today, over two decades on.

Announced in October 1998, the 43P Model 150 succeeded the earlier 140 as the smallest, quietest, cheapest new RS/6000 money could buy, with a base price of only $10,000. Like its predecessor, the Model 150 is designed around the aging but still capable PowerPC 604e, but with some G3/750-era chipset enhancements. The Model 150's low price (for an AIX system,) small size and mind-bogglingly long 5-year production run has made it one of the most ubiquitous RS/6000s ever made, with IBM selling over a hundred thousand systems in all kinds of configurations, from personal desktop workstations to tiny multi-user departmental servers. Today, the Model 150 still commands interest from collectors and hobbyists not only from its plentiful numbers, but its industry-standard architecture and striking monolithic design.
