I recommend you have a system with 16 gigs minmum. You can get by with less but once you start doing things that require you to have a server running and 2-3 clients its starts to really push the system.Maybe a little easier running unbuntu with the GUI rather than from the command line but make sure you got at least 10gigs memory free you can spare for the lab. Unbuntu server is a problem and Debian is a little harder to use than unbuntu. If your money straight you can probably pick up a few chesp laptops at Staples for under 200 and throw Linux on them and get a cheap switch from Amazon for under 25 shipped.
I'm still working on mine but unbuntu server, I can copy and paste to the command line from the host computer.
Also use Twitter and follow that Brian little dude and follow this other dude named David bothal. He has a gns3 course for sale forn40 bucks but it's not really newbie friendly.
If any other you nrehs wanna group chat so we can all learn send me a pm.
