What should I do with this keg?

[Jade_The_Raw]

I got a 15 gal keg for 40$ today! Making it my first piece of brewing equipment!

But... Now I dont know what to do with it? Should I turn it into a HLT or a Boil kettle?

I was thinking about getting these

And does anyone know if this comes with 2 10 gal coolers?

Tell me what you think my next move should be!

I'd turn it into a boil kettle. You can do without a separate HLT if you batch sparge.

^Yeah, and if you wanted you could get a false bottom for it and mash in it. I am finding good success with mine used this way.
