The late 2005 Power Mac G5 was introduced in October, and discontinued in August the next year. There were three configuration options, one dual core processor at 2.0 GHz, one dual core at 2.3 GHz with model number A1177, and one dual core dual processor (quad core) at 2.5 GHz.
I am looking to mod my mac for a recording unit running pro tools. Any information on doing this? Probably not going to work but thought I'd give it a try.
