The Apple iMac G4/1.25 20-Inch (Flat Panel) features a 1.25 GHz PowerPC 7445 (G4) processor with the AltiVec "Velocity Engine" vector processing unit and a 256k on-chip level 2 cache, 256 MB of RAM (333 MHz PC2700 DDR SDRAM), an 80.0 GB Ultra ATA/100 hard drive (7200 RPM), a tray-loading 4X "SuperDrive", NVIDIA GeForce FX 5200 Ultra graphics with 64 MB of DDR SDRAM (AGP 4X support), and support for AirPort Extreme (802.11g) and Bluetooth with optional cards.

The internal components are housed in an attractive 10.6" half-sphere, ice white case with a chromed stainless steel neck that supports a 20" TFT Active Matrix LCD display (1680x1050 native). This model shipped with MacOS X 10.3 "Panther" (and cannot boot into MacOS 9), as well as an ice white Apple Pro Keyboard, Mouse, and Speakers. Unlike some earlier iMac models that are convection-cooled, the iMac "Flat Panel" series is cooled by a quiet internal fan.
