Hi, I just got done with a pc I built for a co-workers daughter. She is a 10 year old. I was challenged to make it cute and cheap so I chose the purple/white case with purple LED 120mm fans and LED lights.
I had the motherboard, psu, and ram already so I bought the rest. The system wasn't built on heavy gaming, just kids games. Lego, Disney, etc. I only charged her $250 for the build!!
