Just the same , the modification makes no diference to the cooling or lack of it. The fact that a DSLR generates heat during exposureis the main reason noise is created on the image.
Most modern DSLR's are capable of 5 minute exposures with ease but do require darks to be taken. You will need to take a good number of exposures and stack them to get the best result.
As to which camera? I would go for the new DSLR. It has a much bigger CCD/CMOS and is very capable of producing great images.
