[CentOS] How to select a motherboard

Not being familiar with chip sets and other factors that "hardware 
experts" understand, I am perplexed with the multitude of available 
motherboards.  Is there a Web site that can be of help or a "strategy"?

My goal is to replace my motherboard with one that is Centos compatible 
and uses a Pentium 4 in the 2 MHz range.  As example, when I go to 
Mwave, I am presented with this list, but I really do not know what I 
should be looking for in the specs.

Any suggestions will be appreciated....
