All SM Malls which has a department store has a CyberZone. You should go to one of the SM Malls that has that cause there are a ton of shops there for Mobile Phones (unlocked), Computer Parts, etc.
But you wouldn't really get the latest trend of Computer Parts there,
what I recommend is going to Gilmore avenue (near Aurora and the LRT Station and also north of Greenhills) to get the latest computer parts.
There is also a level of gaget stores in V-Mall (also called 'Viramall') in Greenhills (level 3 opposite of the food court).
