The SuperMac C500 slimline desktop features an upgradeable PowerPC 603e processor, 16 Megabytes of RAM (expandable to 144 Megabytes) right on the logic board, an internal IDE 1.2 or 2 Gigabyte hard drive, an 8x or faster internal CD-ROM drive, and CD-quality SRS Surround Sound stereo. And all C500 models come with MicroMat TechTool Pro, FWD Hard Drive ToolKit, and FWB CD-ROM ToolKit. Or for a little more, step up to the mini-tower SuperMac C600, which share all of the C500's features but has faster processors, greater expansion capability, and a 33.6 Kbps internal fax/modem. The C600e/200, for example, includes 32 MB RAM, a 12X CD-ROM drive, 10BaseT Ethernet, and an internal Iomega Zip Drive. (Note: the C600e does not include a modem.)
