A Geek Goes Flying

 D’oh. I'm an idiot. I’m rebuilding an old Hackintosh into an AI workstation . I pulled the motherboard from the old Corsair case, removed the Core i5 and 16GB RAM (4x4GB Corsair Vengeance sticks), and set everything up in the CoolerMaster case. Everything lined up nicely and, especially with the extra screws I got, it was an easy, straight forward build. I was confident when I hooked up to mains power everything would Just Work™. It didn’t. Pressed the power button and it seemed to be online: The fans were spinning, the NIC lights were dancing, the power LED was on, etc., but the connected monitor stubbornly reported it was not receiving any signal.  Back in the day, computer cases had a cheap speaker installed, looked something like this: Wikipedia photo of an old timey computer speaker But, no more. Starting with what the BIOS was able to tell me seemed like the natural first step, and Amazon enables almost immediate gratification (not as immediate as popping over to the ne...

I had an old (circa 2012?) Hackintosh, which started life as a Core i5 3570K Processor (3.4 GHz 4 Core), installed on a Gigabyte GA-B75M-D3P  main board (LGA 1155 socket, B75 chipset). Basically, a lightly tweaked version of this moarfish build . The Corsair Carbide 300R case (or, rather, the plastic drive rails) were showing their age, the power supply had a tendency to run extremely - worryingly - loudly, and so it was just sort of collecting dust. A lot of dust (see below). I had picked up a new Cooler Master case and EVGA power supply to rebuild it, but never got around to it. Instead, I eventually moved to a maxed out (1TB SSD, 16GB RAM, Core i7-3720QM CPU @ 2.60GHz) 2012 Mac mini server, running the latest macOS through OCLP. Now that I’ve finally decided to pull the trigger and start getting my hands dirty with “AI,” after flopping around for a minute looking at various options (eGPU chassis hooked up to a 2020 MacBook Air running Linux? $249 NVIDIA Jetson Orin Nano Super De...
