The computer will be ok for a quite big samp server, and things like a webserver etc. The important thing indeed is the internet connection. Below several hundred kbyte/s upload speed it will be quite pointless, also ping will be quite high on home connections. Also, if you got a dynamic ip, getting a static one is a must, at least with something like no-ip.com, or the whole action will be useless.

Also, its not a vps, but simply a server. VPS means virtual private server, and this private server surely isnt virtual.
