mATX vs mITX case size

[silk186]

I will be building a new computer when Skylake drops as it is around the time I will be moving from a nice 1 bedroom apartment to a shared flat in London and I need to downsize from the huge case I have now. I'm torn between mATX and mITX. I was settled on going mITX finally but when looking for something that would accomidate my 280x and an ATX PSU (mine is 150 + modular cables). Reading recommedations for other builds it seems that small mATX cases are near the size of mITX cases like the corsair 250D. Obviously mITX can be significantly smaller but if I go with my 280x and PSU would the size difference be significant?

All depends on the case. Here's a spreadsheet of SFF cases.

Several mATX cases that will fit your parts that are smaller than the 250D but you can go smaller yet with Mini-ITX depending on which model video card you have.
