1) Build a PC that can play 1080p video at 60 FPS without a hitch.
2) Run it all with a CPU, a PICO power supply, and no graphics card so that it can fit into as small a case as possible.
No demanding gaming or rendering is intended to be done on it. It's main purpose is to play Netflix, YouTube, or HD movie files from the hard drive with VLC, all while maintaining the functionality of a PC.
To Somefa and Tek Everything on YouTube for inspiring this build. https://www.youtube.com/watch?v=w37AnZ1eZxE&t=0s&list=WL&index=332
At first I was against an embedded solution, but the J5005-ITX is great. For a good price, you get a motherboard, and a processor and heat sink that do the job perfectly fine. And because there are no fans in this build, it is DEAD SILENT. Perfect for movie watching. I'd say that's a decent trade-off for not being able to change the processor/cooler.
A PICO PSU was an obvious choice because of its small size. I had no experience with PICO PSUs or power bricks before this, which is why it was helpful to use Somefa's build as a reference. While 80 watts doesn't sound like much, this PC barely gets to 15 watts when playing Netflix, according to my Kill A Watt meter.
For the Wi-Fi card, I originally bought an Intel 9260, but couldn't get it to work. The Bluetooth worked and I could get online with an ethernet cable, but there was no option for Wi-Fi under Network Connections. I couldn't figure how to get it to work so I just returned it and settled on the Intel 8265, which works fine.
OPERATING SYSTEM AND DRIVERS:
When installing Windows 10, I didn't even need the DVD that came with it, just the key code inside. You can download Windows 10 for free from Microsoft, put it on a flash drive, and install it on another PC so long as you have a key code.
Once I got it up and running, I downloaded the Intel Driver & Support Assistant to get the current drivers for the CPU and get better performance. YouTube was running really choppy without it.
Also downloaded the ASRock App Shop so I can download any new drivers for the motherboard down the road.
