Need a good, cheap case for an ECS mobo

[caliente]

I plan on using an ECS K7VMA mobo w/ a Duron 800 to build a system for my stepdaughter. Nothing fancy, just a basic internet appliance. Do I need to be concerned with heat? I have a crappy Volcano II that wasn't up to snuff for my 1.2G on a A7V133. What's a good case for this basic sys?

Thanks
