The Hardware Research 604e/200 was a cost-effective rackmount Mac clone released in early 1998. Powered by a single 200 MHz PowerPC 604e processor, it provided workstation-grade performance within a durable 19-inch rackmount chassis. Built on Apple’s Tsunami logic board architecture, the machine offered excellent expandability for video, audio, and scientific workflows.
Outfitted with 128 MB of RAM, SCSI storage, and a 4 MB ATI XCLAIM 3D graphics card, this Mac-compatible clone was particularly popular among server environments and creative professionals who required rack-based deployment and robust Mac OS support.
