For the Full article visit my blog. Recently I replaced my Desktop with small form factor PC. It is an excellent experience when customizing a computer. Now I present you my tiny HTPC that runs MacOS Sierra. It doesn't have any Graphics card because my aim is to make it smaller, so I'm using the Intel HD Graphics. HTPC Specifications Motherboard – Gigabyte GA H270N WIFI Processor– Intel Core i5 7600 Graphics– Intel HD Graphics 630 GT2 RAM– Corsair Vengence 8GB 2400Mhz WiFi & BT– Apple original BCM94360CS2 Card with M.2 NGFF Adapter Case – Streacom F1C Evo WS SSD– Samsung 850 Evo 250GB HDD- 2 TB Seagate 2.5″ Drive Power Supply- HDPLEX 160W or PicoPSU 160xt with 240W Dell AC Adapter Running Mac OS Sierra 10.12.4 Technical Information The motherboard is Gigabyte's H270N WiFi; I replaced the WiFi card with Apple Broadcom WiFi to get all features like AirDrop, Handoff, etc.. For the chase, I went for the Streacom F1c Evo that only fit the motherboard, 2.5 Inch HDD, and power supply. Here I sacrifice the use of discrete Graphics card and use internal Graphics. Because I didn’t want any graphics card. The Streacom Chasis is made of 3.5 mm aluminum, and it is a polished chase I euphoric with this case. Two most commonly used power supplies are HDPlex 160w and PicoPSU 160Xt. These are the best power supplies available for the mini ITX build. In this build, I choose the HDPlex 160W, because it is more recent and more reliable than the PicoPSU. For the AC power, I use Dell 230W power brick to power up the computer. To fit the HDPlex, I have to cut the internal Remote Panel so Just Cropped it equally. Heat is a problem when using stock Intel Cooler, but a 40mm fan is helpful to get rid of the heat. When the PC is idle the temperature at 40C when the PC is Stressed, then the temperature becomes 76C. I'm going to purchase Noctua Cooler. I heard that it is the best Mini-ITX CPU Cooler, I will update this post after getting the Fan. Conclusion Finally, I've Finished the installation of MacOS Serra, and it is working perfectly.
