Mac Mini 1,1 A1176 upgrade (Silverlight sucks)

In 2006, I bought an Intel-based Mac Mini. It had 512MB of RAM, 1.67GHz Core Duo (T2300) and an 80GB 5400 rpm drive, blah blah blah. Over the years I put in 2GB of RAM, then an SSD. Lately, one of its main functions has been playing Netflix and it struggled with anything over about 480p-ish. I put in a 2.0GHz Core 2 Duo (T7200) and it still struggles with 480p! This 7 year old machine can play 20Mbs 1080p h.264 with VLC or “1080p” HTML5 off Youtube, but not 480p Netflix. Yay Silverlight!
