Mine is from 2011 and still going strong. It had some upgrades like extra ram, ssd and a new gpu a couple of years ago and I had to replace the front fan. It starts making a horrible noise about 4 hours into a gaming session with a graphically demanding game, but apart from that it runs perfectly fine. I don’t really play demanding games usually so I don’t really care. When it finally dies, I might just swap out the motherboard and cpu and keep the rest. It’s my personal ship of Theseus.
