On topic, the guys at Mach2 claim replacing the Mini's hard drive with a SSD makes a difference sonically or else they wouldn't swap the drives.
The hard drive is only used for the OS, iTunes, the other music software (like Amarra or Pure Music, or...), and other essential operating software. No music is stored on the SSD. Therefore, it doesn't have to be a large drive. The SSD drive installed in my 2010 Mini is only 40G.
Whether or not the cost is worthwhile in your 2007-2008 Mini is up to you.
