There's a TV in my basement. I want to stream basketball and hockey games down there while I workout. How cheap can I do this?
In my office closet I looked the big Rubbermaid bin I throw random discarded computer components. There was an old ECS motherboard I bought in 2010 that has an HDMI plug! This was a start. It still had an old AMD Athlon CPU attached to it. I found three sticks of DDR2 1 GB RAM, and two ancient IDE hard drives in the same bin. IDE cables! remember those? I had to rip some out of a truly ancient IBM computer that was in the attic too.
Problem is no case or power supply. This was the one thing I had to buy. Microcenter had a super cheap case/PSU for $29.99. Diablotek. Done. I picked it up to save on shipping. To complete the build I found a Dynex keyboard in good shape in the attic, a wired mouse in the basement. Assembled the thing. Throwing on a free license Windows 8.1, and done. Bam.
