Yes I used the Intel® Core™ i5-2400 on it. The build was trouble free and I didnt even have any problem setting up the RAID on it. She is an accountant and had just about lost some customer data by not backing up at all so I made sure that I set up a RAID 1 to ensure she doesnt have that problem agian. From my understanding with the Intel Core i5-2500K it is just a little difference on finding the multiplier and raising if you are trying to overclock it.
