I use a 2008 Dell Inspiron laptop as an office PC. I upgraded the CPU, which would be absurd for a new notebook. I also upgraded to 4 GB DDR2, and an SSD. It still works great!
I think it’s always best to keep things maintained and continue using them instead of buying new things. Maybe some of us have a bunch of old stuff laying around. But what stuff are you still using?
i use a Samsung Syncmaster B2230 as my monitor, going on 12-13 years old and still works a charm for my 1080p 72hz needs
