A co-worker of mine had a roommate move out and leave his brewing stuff behind, including two 5 gallon kegs (pictured below). Co-worker ended up giving them to me for free.

Obviously you need a CO2 tank, and connectors, but what size CO2 tank and are the 'Ball Lock Connectors' the right one in general/these specific ones? Can I use the same cleaning/rinsing chemicals on these (PBW/StarSan)?

Since I am a complete noob to the world of using my own keg, what else do I need?

5 Gallon Kegs

Those are ball lock kegs. You can use PBW (or Oxiclean) to clean them and StarSan to sanitize. Common CO2 tank sizes are 5 gal. and 20 gal. 5 gal. are more portable if that matters to you. I use a 20 gal. and only need to get it filled once a year. Here is some excellent info on cleaning, maintaining, and using kegs....

Thanks! This will definitely come in handy! – tarheel Jun 25 '13 at 2:47
CO2 tanks are measured in lbs, not gallons. As you allude, the size of the tank does not matter other than how big it is / how long it will last between refills. – Henry Jackson Jun 26 '13 at 20:37
I have a 10# tank, it cost me about $20 more originally, but refills at my home brew store are $19 compared to $15 for a 5# tank. – Ugly Dude Jan 21 '14 at 17:13

+1 on this article from Zymurgy. It's great and I refer to it often. The illustrations by Randy Mosher are nice too. – paul Jul 10 '13 at 19:41
