My original plan was to convert it into a working computer by swapping the guts for a Raspberry Pi 4. Malseed used one of the final versions that used Java 5 (the last to support PowerPC processors), which came with some third-party platform optimisation tweaks added by users of the MacRumors forum. A few months ago, I scored a fully working Apple PowerMac G4 Cube on eBay. This continued with the version of Minecraft.
Meanwhile, the RAM saw an upgrade from the base 64MB to the maximum amount of 1.5GB.
The slow spinning HDD was replaced with a faster mSATA SSD, connected via an IDE adaptor. He also replaced the sluggish ATI Rage 128 GPU with a more modern Nvidia GeForce 6200 card running hacked firmware. The G4 Cube was a foray into the business market, as well as an answer to those who wanted an iMac-like machine, with more choice in monitors. Housed in an 8x8x8 cube, the G4 Cube combined the elegance of the iMac with the power of the PowerMac G4. Not the fastest, but a significant performance increase nonetheless. Announced in July 2000, the PowerMac G4 Cube introduced a dramatic new case design. Malseed's machine used an aftermarket Sonnet 1.2GHz G4 upgrade card. With an upgrade card from Sonnet, you could boost this to 1.8GHz. The G4 Cube shipped with a choice of 450MHz and 500MHz processors. You could replace the processor too as it sat on a daughter board. Its internal graphics card was connected via PCI, opening the door to upgrades further down the line. Still, unhappy customers have been asking for replacement enclosures or Cubes, and with good reason, said Technology Business Research analyst Tim Deal. This is something you can't really say about contemporary Apple computers. But, to the credit of Jony Ive, it was remarkably customisable.
