my question is weather or not the slim model 530s can handle a cpu like this with a 250psu, with an already low profile radeon 4650 installed; any other suggestions are much appreciated!
The e6600 you linked is the new model which is a 45nm part, if the Pentium E6600 works then the E7500 works too because they are based on the same newer core ( wolfadale) while the older E6600 is an older core (conroe)
