Ok here is my dilema the only thing that is wrong with the c521 is the motherboard , that is the cpu tested fine heat sink and shroud look like they may fit after all its all going back in a c521 case right , oh yeah the e-521 has two pci slots the c521 has only one plus a pcie slot , its ok because ill be using the on board video. so i dare ask againg and im really concerned abot clearances will the e521 fir into a c521 case? r
Thank you all for the great advise we (the customer) found a HP pav n305a that would suit his needs, reload the os added 1 gig memory and we are off and running. Now i have a carcass laying around , might make a bird house out of it and the bad mobo wall art. But seriously thanks to all.
