Yeah it’s still totally usable, but I just haven’t booted it up more than a handful of times in the past couple years. I built it for software development on Linux (with a little extra graphics capability for occasional gaming) in the era when Apple was making those terrible “touchbar” keyboards. But have since switched back to a MacBook (and a Switch 2 for gaming), and now it’s just taking up space.
That's a perfectly fine modern PC. Similar to or faster than what some of my casual gaming friends use.
The RAM alone would probably sell for $350 or more.
