Here's my two completed mods using powermac G5s that I've been working during the past months. I've been searching the forum for inspiration all along so don't be surprised if it resembles like one of the builds here! The first one is a pretty standard build featuring two gtx 1080s and a custom cooler platform to avoid them getting hot. On the second build I've got carried away and wanted to do an all-in-one solution to put all computers I had around the home to keep them tidy. I attached 6 HDDs, two intel NUCs, one raspberry pi and one gigabit hub (to avoid multiple ethernet cables coming in). Surprisingly, there's still space for more stuff!! I've got heavily inspired in the limo build I saw around here.
