Hi Everyone,
I finally did it!
After 3 months of thinking – which is not my strong point – and one month of waiting for parts from China, my battery powered desktop PC is complete.
I’m very satisfied with the result, especially since I did it with less than 100 USD in parts – you can see the parts list below. 
It can last around 3 hours on battery with light/youtube/video watching and one hour of gaming.
Please like and share this video with your friends (if you like it). It helps a lot with my confidence and pushes me to make more fun and interesting projects.
Thank you!
Gabriel
