I have a spare laptop running Linux Mint. I would like to try running my own instance and sharing it with a few users to help out and for the experience. Below are the specs. Do you think it will be powerful enough, and if so, how many users would it be able to handle? I could restrict uploading of media if that would make a considerable impact.
Dell Inspiron 15-5000 CPU: Intel Core i5-5200U, 2 cores, 4 threads RAM: 8GB Storage: SanDisk SSD Plus 1TB
You could get a second static IP address from your ISP to keep it isolated from your home network. That may require additional hardware.
So yeah, probably cheaper to use a cloud based solution. Unless you want the experience of setting that stuff up.
