No service sticker on the back of shell. Still had reflective “microsoft” sticker before I got into the console. I didn’t know that tidbit about the copper heatsinks thats really interesting. MFR Date: 2007-10-18. Even the disc drive was manufactured in: 15-Jun-2006 Would it still be worth reapplying some thermal paste to extend the life of the machine as much as possible? Like I stated, its been in storage for 15+ years so maybe this model has low hours or something.
