I would go ahead a change the HDD's as they are still running ok but who knows for how long ?
I'll leave it to the Pro's for suggestions on what to replace HDD's with.
Tell us about the PSU , you may also want to replace the PSU to a more modern , power saving one .
After so many years PSU's tend to get weak.
Hi! I just turned my 6yr old entry-level gaming computer into a htpc running 24/7 using plex. for the past 6 years its been running 6-12 hours a day. I did some maintenance On it first and got rid of all the dust, changed Intake and exhaust fans to silent ones, mounted a coolermaster evo 212 with silent fan as well cause stock fan was a jet engine, and changed thermal paste on CPU and GPU.
I was wondering, because the PC is getting older, if there's any other parts i should change to keep it running smoothly for the coming years. It has a Radeon 6850HD GPU, intel i5-2550k processor, Silver Power Gorilla 500W and 2 seagate barracuda HDDs, 1 and 3 TB. Anyone know the average lifespan of these components? I'd especially hate the HDDs dying on me..
