When I connect the Mac Mini, the fan keeps running but there’s no visible sign of activity—no lights or screen output. After upgrading the CPU and RAM about a year ago, it functioned properly for a month, but after I disassembled it, the build looked similar to a broken machine and stopped working. It might be related to the power supply, though I’m unsure. I don’t plan to send it to a repair shop since this is my personal project, and any advice would be invaluable. Thanks for the help! …… Forums :}

Observe the unusual aging parts popping up, like swollen capacitors and similar issues. See how the plastics are turning a dull yellow. Treat this as a retro machine. Edited August 16, 2022 by Bombastinator
