I have an early 2000s PC (pre-SATA) with 512MB RAM (I’d love to tell you about the CPU, but its under a cooler that isn’t going anywhere) that’s been sitting in closets for about 15 years. Assuming I’m willing to buy into it, can something like that reasonably host the following simultaneously on a 40GB boot drive:

Or should I just get new hardware? Regardless, I’d like to do something with this trusty ol business server.

Edit: Lenovo or Dell as the most cost-effective, reliable self-host server in your opinion?
