Ideal Home Lab for MCSE?

In the next few months I will start studying for the 2003 MCSA/MCSE certification. I want to set up a home lab to study with instead of paying thousands for someone else’s lab.

What type of hardware and/or software would you recommend?

If I bought a certification book it might tell me there, but I haven’t purchased a book yet. I’m sure someone has asked this before but I haven’t found any reference to it. Thanks for your help.
