First of all have a brief look at xda threads about compiling rom from source dont follow all stuff from there tho.. just have a look on those threads specially that jackeagle thread. 

now first what you need :
    If on local
   -> Fast internet connection (fast enough to download 50GB rom source without waiting for a day or two xD )
   -> 4core cpu(or higher)
   -> 8gb minimum ram 
   -> Linux (Ubuntu for this guide)
