hello,

i purchased the following parts:

i faced problems when trying to mount the motherboard, so i had a technician assemble the pc for me, he called me later saying there is a problem with the mobo, that its too small for the case, the gpu once mounted on it wont fit in the socket designated for it at back of the case.

he said i should order another mobo, a gaming one would be better to match the parts i ordered.

what do you think? should i change the mobo? or change the techi?

thank you, i'll pick best answer to close the thread.

Your MB is the mATX format, and the case is compatible Mini-ITX, mATX, ATX case, the mini-ITX is even smaller than the mATX, I never hear the MB is too small to fit the case, only too big to fit the case. From this point you may think about to change the tech person. The problem maybe the case back panel GPU slot does not lineup to the GPU, you can ask the tech person to make sure that, otherwise or retune the case.

Your case can fit the 295mm GPU with drive cage, 430mm without the cage. And the GPU size is 282mm.

The GTX 780 GPU is effectively a "two-slot" card inasmuch as it sits in one slot and renders the adjacent slot unusable on account of the GPU thickness. Therefore it requires a full-size ATX motherboard to accommodate it, whereas the board you've bought is a micro-ATX which is shorter so has fewer expansion slots.

So the technician is correct, you need to buy either a different board or a different GPU for the existing board.
 
WOW, this is my first time to see that " Therefore it requires a full-size ATX motherboard to accommodate it (dual slot GPU), whereas the board you've bought is a micro-ATX which is shorter so has fewer expansion slots."

The B85 has other two pcie2.0 that means if the OP does not the pcie2.0 he/she can use the three-slot GPU too, because the GPU will block those slots. I add the link for similar MB/case with HD5970 ( dual slot GPU too), looks at those, you does not need the big size MB for the dual slot gpu as long as the case can fit the long and dual slot GPU. http://www.thinkcomputers.org/asus-m4a88td-musb3-amd-880g-matx-motherboard-review/4/

If the MB like this Mini-ITX http://www.techscreens.com/zotac-announces-7-series-mini-itx-motherboards.html then the dual slot GPU will not fit.
