Having Fun w/ (Taking Apart) a Gigabyte (GB-BXA8-5557) Mini PC

These photos were taken in my garage when I decided to take the mini-pc apart and apply a different thermal compound (arctic ceramic). Also I wasn’t sure if this unit used a GPU on the processor or if it had a dedicated GPU. It looks, as you can see, like this unit does have a separate GPU board connected by a mini PCI Express connector card (seen on the side of the motherboard in the motherboard & heatsink pictures).

      I’m not sure you’ll get this reply as you posted this a long time ago but here’s my two cents on this anyway. I think what happened here is Gigabyte sold two versions of this model. One with just the APU (AMD A8 5557m with Radeon 8550g) and another with a dedicated GPU (AMD R9 M275x) along with the APU. The “disabled/fake” GPU uses an MXM board with a hole in it from the motherboard that only supplies power to it and that power is used by the case fans. So it’s not a “marketing cheat” unless you paid extra for the model with a dedicated GPU. My guess is that when bad GPU’s came off the assembly line they re-used them as power relays in this model for the case fans rather than just wasting the failed chips and PCB. I did not buy the model with the dedicated GPU and I received what was advertised in mine which was an A8 5557m APU with Radeon 8550G. Hope this sheds some light.
