Also, if I compared the HD speed of a Mini and the HD speed of an iMac, how much more better would the iMac HD perform? I think it's 7200 RPM vs. 5200 RPM.
in this case (if you mean the iMac G5) there is not only the difference in RPM but allso what interface is been used...
Mac mini uses PATA equal to the type in i&Powerbooks wich is if I recall correctly allready a slower type than the PATA used in desktopcomputers like the iMac G4 & PowerMac G4
the iMac G5 uses SATA wich is allso found in the PowerMac G5, and that has a broader bandwith added to the faster RPM of the drives...
you can add a 10k rpm drive in the iMac... or go for one with 16MB buffer... that allso will speed it up...
just compare the fastest iMac to the fastest Mac mini
1,42Ghz G4 vs 2Ghz G5
busspeeds I would have to check but G5 will have a faster bus
1GB ram max vs 2GB ram max
PATA laptop HDD vs SATA desktop HDD
...
as long as you don't break things the warranty will not be void on both computers... but I don't have the fineprint for all the details concerning warranty...
