I just refurbed my '09 13" MBP. New thermal paste, cleaned the intake/exhaust, new battery, replaced the battery indicator/sleep sensor (ribbon cable got damaged). All in: ~$70. It still has 8 GB RAM and an SSD from my previous upgrades. It runs El Capitan just fine, and the fan is barely audible. I'm going to be so disappointed when I eventually drop cash on a rMBP, knowing that I'll never be able to do all of that in the future.
