Thanks to all who replied on this and you were many. Below is my
original post. The unanimous consensus was that it's not a problem if
you verify that the current draw and power consumption of the
replacement is less than or equal to the old drives. Particularly
with newer drives that consume less power and therefore dissipate less
heat you should be fine. Several people cautioned against putting 2
drives in the case at all and suggested it would be better to replace
both 104Mb drives with a single drive of higher capacity (e.g. 1Gb).
This elimination of the 2nd drive creates more space for air to
circulate.
