The case is where all the parts in the system unit are housed.  The common "form factor" for today's cases is ATX, however.  Then there is the "size" of the case. There are Micro-ATX, Mid-ATX, and Full-ATX.  Micro-ATX is smaller and therefore has a lower profile, however they are not much fun to work on or upgrade.  Mid-ATX is a happy medium.  Full ATX takes up A LOT of room.  If you are the techie type and want to see how much stuff you can cram into one system this is the way to go.

When upgrading the case just make sure your motherboard will fit into it.  For instance, an ATX motherboard will not fit into most micro ATX cases.  On the other hand, most Mid and full size cases will also hold a micro ATX motherboard.

Choosing a case isn't hard once you learn about the form factors and power requirements of modern systems.  You can find bargain basement cases for as little as $20.00.  Wiz-bang all aluminum  tool less entry name brand cases (Coolmax) can run you as much as $300.00 or more.  The more expensive cases tend to have some nifty bells and whistles.  Better cooling is often part of the added value.  Just make sure that your case has enough "bays" to handle the hardware you want installed.  Many micro-ATX cases come with only one 5.5 inch and/or one 3.5 inch external bay(s).  While this may be fine for you current intentions, future upgrades will most certainly include a new case.  Swapping cases isn't difficult, but it is time consuming.

 

A Word On Power Supplies
Power supplies are often built into the case.  You need to make sure the power supply can handle the load you plan to put on it.  Smaller, less expensive systems, typically do not need as much power as a high end system.  Make sure to check with the suppliers of your hardware for power supply recommendations.
