OK first off that is a server board which requires lots of air movement across its board.
They were designed to be placed in either pizzabox ( err rack mounted cases ) which use ducts usually with high powered fans pulling air in from the front and blowing out rear.
To compensate for that, you will need a case which can either blow a lot of air from the front or top, or find an old case which can still draws air from the side, and pair them with high powered fans again, so your board and ram do not overheat.
That type of setup is not recommended to go budget... infact nothing with the word enterprise is typically associated with budget, unless its EOL.
