Very small MATX lan build

I am thinking of building a small system that I can put in my backpack. As far as I am aware all the parts will fit, be sufficiently powered, and won't choke if I take out the unused Expansion slots on the back for the Gpu. I am not looking to do any overclocking. Any red flags besides cooling? I also don't know if the PSU has a efficiency rating. 

Looks fine.  I wouldn't expect much from that PSU, though, as it's not 80+ certified and is probably cheaply made.

Do you know of what type of psu sould I get I know a normall ATX wount fit?

SFX/Micro ATX.  depends on the case, really.

Thankyou a ton the PSU was My only prablem.
