Difference NEC 5543 and 7543?

Apart from RAM on the 7543, is there anything else?

Does anyone know if a front bezel from a NEC 6500 fits these new drives?

Will be using it with a Dell D series Latitude (D410)

Thanks for any info

DVD-RAM should be the only difference between 5543 and 7543. However I haven’t seen a 5543 drive before - only 5540, 7540 and 7543

Thanks Liggy, always there with a helping hand.

Once again appreciate all the time you spend on CD Freaks.
