56k modem !
what decade are you in ?
Anyway, you don't need any of the items you listed, once you have your first machine, that is.
The modem is so you can keep mining after your ISP drops you like a hot potato for "illegal" activity. The prudent would be working on setting up open mesh networking, but that takes time.
Note: the cheap dial-up plans are often limited to 20 hours/month.
