let me add another suggestion to the flood: once you've rebuilt the  
box, install DenyHosts (http://denyhosts.sourceforge.net/).  this  
tool is quite effective at blocking brute-force ssh attacks; not only  
will this make it much harder for an attacker even if you should  
happen to set a weak password on an account in the future, but it  
will also reduce the amount of CPU time and memory wasted on dealing  
with brute-force ssh attacks.

RPMs are available at sourceforge; the python 2.3 RPM works great on  
CentOS 4.

i'm sorry you're having to deal with this. :(
