November dual 1.8 GHz also has 512 MB DDR400 and an 8 GB maximum. DIMMs are installed in matched pairs. Each configuration retains its stock drive and graphics at base and maximum memory.	64 MB supplied in two 168-pin DIMM sockets, no soldered system RAM; up to 128 MB using 5 V buffered EDO DIMMs. The original brochure and service source specify 60 ns or faster EDO memory, while the exact support database lists 70 ns.
Storage type
Storage type	Stock 80 GB on the single 1.6 GHz; 160 GB on the single 1.8 GHz, dual 2 GHz and November dual 1.8 GHz. 7200 rpm Serial ATA drives; two internal bays with 150 MB/s interfaces. One optical bay with 4x DVD-R SuperDrive; optional Combo drive and 80, 160 or 250 GB drives.	Original US Home Edition M6079LL/A and Canadian launch configuration have a 4 GB IDE drive, 12× tray-loading CD-ROM, 1.44 MB floppy and 100 MB Iomega Zip drive. Later Americas configurations documented by Apple have 6 GB, 24× CD-ROM, Zip and a 56.6 Kbit/s Apple/GV modem with Mac OS 8.0; Latin America uses a 33.6 Kbit/s modem. European 6 GB/24× configurations include video input, TV/FM tuner and Avid Cinema. These are regional configurations of the same 300 MHz model.
Expansion slots
Expansion slots	AGP 8x Pro graphics slot. Single 1.6 GHz has three 64-bit 33 MHz PCI slots; faster original models and the November dual 1.8 GHz have PCI-X slots, two at 100 MHz and one at 133 MHz.	Two PCI 2.0 slots for approximately 7-inch cards with Mac drivers, plus Communications Slot II, video-input slot and TV/FM tuner position. The original Home Edition's modem occupies the communications slot; its Zip drive occupies the pre-cabled 5.25-inch internal SCSI bay. Apple specifies five external SCSI devices with Zip fitted.

The shared service manual gives 20.18 kg without the CD-ROM; standard complete-unit weight remains unresolved and the headline mass is omitted. Gallery monitor is optional.
Power supply
Power supply	–	Exact support database and original brochure give 220 W maximum continuous, 100–125 or 200–240 V AC at 47–63 Hz. The shared Service Source instead gives 140 W for the 6500 and 90–130 or 180–264 V; the conflicting ratings are retained, and neither is treated as measured operating consumption.

In the box
In the box	Original models shipped with Mac OS X Jaguar; the November dual 1.8 GHz announcement includes Panther. Apple’s 18 August 2003 shipping release confirms immediate availability of the single-processor models; the original dual 2 GHz was due later that month.	Exact support page lists original software 7.6.1; later regional configurations use Mac OS 8.0. Apple lists 4 April 1997 as introduction, while its Canadian announcement promises limited supply later that spring. The maker's 1997 ordering brochure and contemporary shipping-system list establish retail sale in 1997, but the actual first-sale month remains unresolved.
