Sounds fine.

I don't think it will make that much difference, but it is the
principle of the thing that counts. After all, if you compare
the prices of the CAS5 and CAS6 modules, I bet there is a
price difference. So you're receiving something of less value
in exchange, as the CAS6 should be cheaper for Dell to provide.
