Honestly, how many such old machines are going to be installed with Mandrake ? I didn't see a machine unable to read 700MB ISOs in a very long time. If the box is unable to read them, then probably Mandrake isn't the best choice for it anyway - low memory, old CPU and such.
You're not going to make any enemies by giving 650 MB CD's to a user with a new machine. You will make some enemies by giving 650 MB CD's to a use with an old machine, especially in the server/laptop market, which is where Mandrake could use some more penetration.
This is a perfect incentive to make a one or two DVD set and sell them. If people could order a FULL two DVD set (cheap, without books or boxes), this would be very cool, and generate some profit.
