~$1300 mATX build

[Termie]

The bend of the ribbon cables made it physically unlikely, if not impossible (although the motherboard came with a single straight connector). I'll look into brute force for next time. How much space does that slot have? I may use a rubber pad to elevate the HDD if they both fit.

The lower bay has space for a 3.5" and a 2.5" drive. If the 2.5" slot doesn't work for you, you can use a bay converter to mount 2.5" drives in the space for a 3.5" drive.
