What Motherboard is it using?

@tgmmryoutube not sure what specs you are looking for. There are different variations of this model with different specs. So you'd have to be a bit more specific. The basic configuration for the motherboard are Processor Speed 1.1 Gigahertz

Processor Type Intel Pentium Celeron 847

Processor Cores Dual-Core

Processor Cache 2MB

RAM Type DDR3 SDRAM max 4GB possible

Alos, why would you think about using the parts for a desktop. You are going to be pretty disappointed. Just attach an external monitor and keyboard/mouse to it instead of trying to place parts of it to a desktop.
