I looking to upgrade my CD drive to a SuperDrive I can then upgrade to Tiger and more fully use iLife and etc. At OWC they offer... a Pioneer 16X DL SuperDrive DVR 111D (DVR-111D-BK) for $48.99 and... a Pioneer 16X DL SuperDrive DVR 110D (DVR110D) for $44.99 IÕm upgrading my Power Mac, G4, ÒQuickSilverÓ, 733 MHz with a L2 cache of 256 KB and a bus speed of 133 MHz. ItÕs Memory is maxÕed out at 1.5 GB and itÕs Boot ROM is version 4.2.5f1. The CPU is a Power PC G4 (2.1). So what are the differences between the two units and which is best suited for a QuickSilver? As always I wait your insights... Rich
