The Apple Power Macintosh G4/1.25 DP (Mirrored Drive Doors) features dual 1.25 GHz PowerPC 7455 (G4) processors each with the AltiVec “Velocity Engine” vector processing unit, 256k “on chip” level 2 cache, and 2 MB of DDR SRAM level 3 backside cache. It shipped configured with 512 MB of RAM, a 80 GB Ultra ATA/100 hard drive, a 2X DVD-R/CD-RW “SuperDrive”, and a 4X AGP ATI Radeon 9000 Pro graphics card with 64 MB of DDR SDRAM. AirPort (802.11b) was available by custom configuration. The Power Macintosh G4 (Mirrored Drive Doors) series, so dubbed by Apple because of the “mirror finish” on the drive bay doors — but often called “Wind Tunnel” by users referring to its noise — was based on the architecture used by the Xserve G4. Compared to the “Quicksilver 2002” series that it replaced, the Power Macintosh G4 “Mirrored Drive Doors” models all add dual processors with level 3 caches and an analog audio input jack. The low-end Power Macintosh G4/867 DP (MDD) uses faster PC2100 DDR memory and the higher-end Power Macintosh G4/1.0 DP (MDD) and Power Macintosh G4/1.25 DP (MDD) have faster 167 MHz system buses, use faster still PC2700 DDR memory, and have superior graphics cards as well. Like all previous Power Macintosh G4 models, the “Mirrored Drive Doors” line uses a case design effectively the same as that introduced with the Power Macintosh G3 (Blue & White) — complete with a fold down door on the side that makes upgrading very easy — but its silver like the “Quicksilver” models and adds the aforementioned mirrored drive bay doors along with four decorative indentions on the front reminiscent of the “Ventiports” on a 1949 Buick Roadmaster
