After doing some homelabbing I started looking into the idea of micro datacenters and somehow that led me to thinking about vps hosting. I have several mid to high tier desktops and I contemplated just starting with trying to sell off of them using proxmox and a dedicated fiber line. Is this an ok way to go about this venture to start until I can invest in proper server hardware? Or should I jump right in and get a rack unit? I ve done some research on cpus and parts everything seems very expensive on anything current and Its hard for me to tell how viable older gen parts are for what im trying to do.
