economical laptop

[Kalyan Vaidyanathan]

Hi,
  I'm trying to figure out the most economical way to get a functional 
laptop.

  I've never done anything like this before, but am willing to learn.  I 
would like to know if building one from parts is cheaper than getting a 
regular laptop that I can upgrade over time (more RAM, bigger harddisk 
etc.).  If building from parts, are there any recommendations of where I 
should start from?
  Ideally I'd like about 60GB harddisk, 512MB ram, >2GHz processor.  The key 
requirement is a wireless network card so that I can use the laptop anywhere 
at home.  Software, I plan to stay with linux.  I've only worked with RH9.

TIA for all recommendations,
regards,
-kalyan
