Like their predecessors, the "chassis" of the "Ambient Light Sensor" iMac G5 models rest upon an aluminum stand with an adjustable hinge, and it supports 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. Additionally, as the name implies, all "Ambient Light Sensor" models have a sensor under the edge of the display that dims the sleep indicator light when the room is dark -- a nice touch for a system setup in a bedroom.

The iMac G5/2.0 17-Inch (ALS) features a 2.0 GHz PowerPC 970 (G5) processor with an optimized AltiVec "Velocity Engine" vector processing unit and a 512k on-chip level 2 cache, 512 MB of 400 MHz PC3200 DDR SDRAM, a 160 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading 8X DVD-R/CD-RW "SuperDrive", ATI Radeon 9600 graphics with 128 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 standard AirPort Extreme (802.11g) and Bluetooth 2.0+EDR.

The iMac G5 models are 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.

Despite the age of this system, site sponsor Other World Computing has RAM, hard drives, SSDs, and other upgrades available for this specific iMac while supplies last.
