I have a server in my office that's at from 2009 still far more economical to run than buying any sort of cloud compute. By at least an order of magnitude.

Perhaps if you only need to run some old PHP app.

What kind of disk and how much memory is in there?

72 Gigs of Ram, 4x SCSI 15K drives I think. Yeah, I mean it's not doing anything crazy running a lot of virtual machines, random servers, probably the most intense thing is video transcoding. It works well though and like I said way way cheaper than running the same stuff on cloud infrastructure. I think I bought it for like $500 about 10 years ago. I started saving about $76 a month just off of moving Virtual Desktops off of AWS to that when I got it so easily paid for itself in a year.
