I don't think so. When I changed from the G5 Tower with most drives sited internally to the mini with external drives, the first thing I noticed was how much quieter and cooler everything ran. Never did the detail analysis of power consumption, it would be difficult to pull the computer consumption out from all the other systems and devices running in my home on a near continuous basis. In my brother's working environment, noise is a serious problem. That's the biggest downside to the Mac Pro for him: when it gets busy, the huge cooling system throughput requires a massive sound box, with its own noise managed airflow system, to keep the noise from being a problem. I can hear the mini's fan running at peak only once in a while, with no sound shielding at all. It could be sound shielded into a tiny box at minimal cost in space and such. The design model of one big power supply to power all the peripherals is the usual "single point of failure for all devices" game too: if all your peripherals are inside the Mac Pro, and its power supply spikes, you stand to lose them all. With my external peripheral system design, I can have drives selectively powered as needed, and any one of the individual devices going belly up is unlikely to have any permanent effect on any other device. Even with all six drives running, several are on average in power saving "parked" mode so the total noise involved is much much lower, overall, in my office environment. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
