Apple iMac G5The Apple iMac G5/1.6 17-Inch, along with the simultaneously introduced iMac G5/1.8 17-Inch and iMac G5/1.8 20-Inch, features a revolutionary design with the entire computer placed behind the flat-panel display in an integrated all-in-one enclosure approximately two inches deep.

Like the aluminium-clad Apple Cinema Displays, the "non-iSight" iMac G5 models are suspended by an aluminum stand with an adjustable hinge, and support the "Video Electronics Standards Association (VESA) mounting interface standard" which makes it easy to mount the system directly on a kiosk, wall, or articulating arm.

The Apple iMac G5/1.6 17-Inch shipped equipped with a 1.6 GHz PowerPC 970 (G5) processor with an optimized AltiVec "Velocity Engine" vector processing unit and a 512k on-chip level 2 cache, 256 MB of 400 MHz PC3200 DDR SDRAM, an 80 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading 8X DVD-ROM/CD-RW "Combo" Drive, NVIDIA GeForce FX 5200 Ultra graphics with 64 MB of DDR SDRAM (AGP 8X), and built-in stereo speakers underneath the 17" TFT Active Matrix LCD (1440x900) display designed to "bounce sound off the desk below". Connectivity includes Firewire "400" and USB 2.0, as well as support for AirPort Extreme (802.11g) and Bluetooth with optional cards.

The iMac G5 series is cooled by three "ultra-quiet blowers that draw cool air into the system" through the speaker grill and a slit in the top of the back of the case allows heat to dissipate.
