Welcome to HBT. Brewing is great fun and relatively easy. Yes, you can keg beer rather than bottling. What most home brewers do is use 5-gallon cornelius (corny) kegs which can be purchased used from a variety of sources. These kegs fit nicely in refrigerators or converted chest freezers, along with CO2 tanks, regulators, etc.
You can do a search in the DIY section for a number of kegging set-ups.
I bottle my beer - I personally don't mind bottling, but lots of people hate bottling and love kegging.
Now go out there and brew. You'll like it.
