Transfer dell MB into another case ahahahh?

I have a dell dim 3000 . Wanted to transfer to another atx case. Well i bought the case and tried putting motherboard in but alas there are no holes for the processor You see the processor is anchored to the case wtith four screwsin the dell case. if you can believe tha!t awfu!l Well the new case doesnt have them to anchor processor. what do i do? I did screw the processor in directly to MB but pc never started. Didnt use grommets because there was no holes in chis for them
