Today we're tackling the last of the Cursed Mac's gremlins - a sketchy original power supply which was literally hack-sawed apart by the previous modder, and barely provides enough power for all of our mods. To do so, we're going to modify a modern Seasonic ATX power supply to cram 300W into this little guy. I hope you enjoy white-knuckle soldering, because one wrong wire and I'll wind up blowing the whole thing up!
