Mechanic and classic computing fanatic Rick Norcross has turned a traditional Apple iMac G3 into the housing of a contemporary sleeper construct — making room for an AMD Ryzen processor and its motherboard with a shift to a flat-screen built-in show.
“My spouse wished me to construct her a PC however did not need your typical PC case,” Norcross explains of the venture. “[I] discovered a damaged [Apple iMac] G3 on [a] market and gutted it down to only the plastic and the steel plate. [I] match a full mATX PC with energy provide inside. The spouse performs on it and loves it.”

Launched as merely the iMac, again in 1998, the iMac G3 and its successors are probably Apple’s most iconic methods. The computing {hardware} is hidden away contained in the housing of a cathode-ray tube (CRT) show, which is created from translucent and the client’s alternative of 13 completely different colours of plastic — 1,000,000 miles away from the minimalist design ethos of recent Apple, and mirrored within the “Aqua” person interface of the corporate’s early Mac OS X releases.
A 32-bit 233MHz PowerPC G3 processor and 4GB laborious drive does not get you far today, although, which is why Norcross pulled out the damaged internals in his market discover and changed them with one thing extra fashionable: a mATX motherboard internet hosting a 64-bit, multi-core AMD Ryzen processor. Whereas the motherboard matches within the case, the ability provide was extra of a battle — and, Norcross admits, discovering a flat-screen show of the proper measurement and facet to suit the place the unique CRT lived was an actual problem.

“We wished it to play the unique Mac startup sound once we hit the ability button, so I purchased the Adafruit Audio FX sound board,” Norcross provides. “With this board you’ll be able to add .wav
sounds which might be triggered with floor enter on one of many pins. The issue with floor enter is there isn’t any momentary floor output off the motherboard so far as I may discover. So, I added a second micro-switch subsequent to the ability button that triggers floor to that pin. The Adafruit FX sound board additionally has a in-built 2×2w amp, so it doubles as a system speaker amp.”
