A tech enthusiast has built a replica of the Cray-1, the iconic 1970s supercomputer, using 30 Mac Minis considered obsolete by Apple. The project, covered by Ars Technica, recreates the machine's distinctive curved cabinet shape while giving the retired computers a second life. Retrocomputing fans are sharing the story and praising the creative reuse of hardware Apple no longer supports.

Why now: The clever combination of retrocomputing nostalgia and e-waste reuse is delighting tech communities.
