You can probably find another board but will also need to replace:
the power supply
the heastsink assembly and fans
Along with purchase a retail copy of Windows (the OEM copy will activate only on the Dell board).
Case,power supply and gpu has been changed i want to know if the mother board only has to have a 1150 socket or i need to look for something else
You'll need a board that supports the CPU you have -- not all 1150 boards have the same CPU support. And as above, you won't be able to re-use your existing Windows license on a non-Dell board.
