DIY PC
I’m a laptop guy but I like to have a fast PC that can run macOS Catalina and Big Sur since I don’t use Windows 10 much. On this post, I’ll show how I select the components and set up the files for booting Catalina and Big Sur.
My sister’s PC died due to bad power supply, it’s been over 10 years. When we push the power button, the cpu and case fans were on but the motherboard doesn’t power up. We ordered a new power supply from Amazon for $25, replaced it and everything is fine now.
My daughter wanted to play high resolution game on the small Dell DT 3668 PC we bought last year. The power supply is too small and under powered. I need to customize it somehow. We need a 12V relay – Inputs are from the 12V off the Hard Drive connector – The 2 output pins […]
These days, it’s hard to find wifi – bluetooth combo for desktop without paying a lot for it, especially the ones that supported by Mac OSX if we have a Mac Wanna Be. The half mini pcie wifi – bluetooth combo for laptops are sold everywhere. So, the best is to get one and use […]

Snow Leopard 10.6.8 will have full QE/CI/CL with Nvidia GS8400 but NOT HD3000 on board (full resolution though). Lion & Mountain Lion […]
I’ve just built a budget system ($400) i5 2500k, GA-H61MS2H for Windows 7 and Mac Lion 10.7.3 because our i7 920 1366 x58 motherboard died. To replace a new x58 motherboard would run me about $120 – $200 and the system will hog over 189W when I encode a movie, it was fast but I […]
A few weeks ago, my son told me his computer died, the i7 920 I built many years ago, I know the motherboard died, not the CPU, but the cost of getting a new X58 1366 is almost the same as getting a new set of Sandy Bridge i5 2500k and H61 motherboard, therefore, […]
