how to build atx

Hello.

Does anybody have any idea, how to build an 200w ATX power supply for PC? I need +3.3v, +5v, +12V, 5VSB output. I found a website which is www.pavouk.comp.cz/hw/en_atxps.html However some technical data of inductance T1, T,L1,L2,L3,L4and transformer T2,T3,T4,T5,L6 are missing.Can anybody tell me what are the values for those compoments, or give an interesting link? Thanks.
 

It is not a trivial task.
You'd have to design all those small magnetics elements from the scratch - not a good design example to start with.
