Hi All... I know this topic is probably old news... I have had my SAT-T60 for quite a few years, and have it upgraded with two 120GB drives for a total capacity of "up to 212 hours"... That's about all I have done to it... No ethernet connectivity... No cachecard... Works fine, and very happy with it... I am in the middle of rearranging my audio/video set up and started to think about whether I would benefit from a cache/ethernet card... Honestly, I would probably not even be thinking about this, but just got triggered by this "project"... I already have a CAT5 cable run to my living room...it feeds my XBox360...and could also feed my Wii if it weren't for it's built in wireless capability... Any feedback? What am I missing?
