The G4 Digital Audio can be easily distinguished from other G4 towers. It is the last of the graphite coloured PowerMac G4s, the next range - the G4 Quicksilver - came in a silver case. All these speeds are unique to the Digital Audio range, with the exception of MHz, which was also an option on the first range of Quicksilvers.
The rear of the G4 has two audio sockets which are aligned horizontally from the top of the port panel. Turn the machine off and open the side of the case. Internally all G4 Digital Audios have three memory sockets black in line sockets - see picture towards the top of the case. It is the only graphite G4 PowerMac to have three memory slots. You will also notice five differing expansion sockets. The first of these is a brown socket which is called AGP, and is used exclusively for graphics cards.
The other four sockets are for PCI expansion cards. If you are still unsure you can contact us on or by email for confirmation.

Apple originally planned to ship the MHz configuration in October , but they were forced to postpone this because of poor yield of the CPUs. In response, Apple reduced the clock speed of the processor in each configuration by 50 MHz making the options MHz , MHz and MHz , which caused some controversy because they did not lower the original prices. The PCI variant was discontinued at the end of It was also the first personal computer to include gigabit Ethernet as standard.
PowerMac G4 Digital Audio Upgrades
Zip drives were optional on all models. These models also introduced Apple's proprietary Apple Display Connector video port. A new line with a revamped motherboard but the familiar "Graphite" case debuted on January 9, Motorola had added a seventh pipeline stage in the new PowerPC G4 design to achieve faster clock frequencies. The number of RAM slots was reduced to three, accommodating up to 1. At Macworld Expo New York on July 18, , a new line debuted featuring a cosmetically redesigned case known as Quicksilver , and various upgrades to the specifications.
The MHz model was notable for not having a level three cache. Quicksilver received criticism in MacWorld's review for removing the "eject" button and the manual eject pinhole, as well as the pass-through monitor power plug, and for the base specification of MB RAM as being insufficient for running Mac OS X.
This was the first Mac to reach 1 GHz. Again, the low end MHz model did not include any level three cache. All models were available in dual processor configurations running at MHz , 1 GHz or 1. A single processor 1. The last real update to the Power Mac G4 line was on January 28, offering dual 1. Between that, its low price-tag, and the delayed availability of Power Mac G5s, it proved a strong seller for a relatively short time. Production stopped on June 27, and the remaining inventory was liquidated, ending the year legacy of Classic Mac OS support with its discontinuation.
A limited range of serial numbers of this model was noted for a noisy fan, earning them the unofficial designation " Windtunnel G4" in some communities. Noise complaints became such a problem that Apple later replaced the machine's power supply PSU and primary cooling fan with quieter versions, and initiated a voluntary do-it-yourself DIY replacement scheme for all previously sold machines.
It is believed  that the reason for the problem is a bug in the CPU with handling cache coherency in dual cpu setups when switching the CPU to low power states. In a low power state, each CPU would have only consumed about 5 Watts  or even less when switching to even lower power states , making for 10 Watts needing to be cooled.
But when run in full power mode as to circumvent the cache problem , each CPU does consume about 50 Watts making for a total of Watts  —essentially the upper limit for which the cooling system was designed, making the fans run at full speed, even when the machine is mostly idle. Soon after suggesting that hack to Apple, a new firmware was released,  disabling the API for switching between single and dual CPU modes.
At least some MDD models also have a design flaw resulting in noise in the audio-out, picking up interference from the mouse, graphics card, hard drive and other hardware. According to Apple, this is a ground loop issue, and only occurs when used with professional balanced signal audio equipment,  however some audio experts contended it is due to shielding defects on the motherboard and affects all equipment.
