The Mirrored Drive Door (MDD) G4 (PowerPC 7455) again changed the outward features of the G4 tower, but unlike the Quicksilver upgrade, the inside of the MDD also received many improvements. It supports four internal hard drives at up to 500 GB capacity each. In addition to the expanded hard drive capabilities, the MDD G4 supports two optical drives. Also, the fourth RAM slot returned to the MDD G4, once again allowing 2 GB of RAM to be used, but this time the RAM is the high-performance DDR RAM. The 3.5-MM audio-in port reappeared with the addition of a 2nd audio jack in the front. These are the fastest G4 towers able to boot up into Mac OS 9. The MDD G4 has only been matched recently in terms of drive expandability by the Mac Pro. This MDD is the best computer for OS 9 users and muscle enough for most current computing demands.

Our Guarantee:

Each used Mac comes with a 120-day warranty, plus these additional benefits:

First, if it arrives and isn't working as it should ("DOA" is definied as within 72 hours of receipt), we'll send you a return shipping label and replace it at our expense (some conditions may apply). Second, if at any time during the first 60 days after the purchase of a pre-owned Mac you wish to send it back for any reason, we'll credit you the current sale price for the item toward the purchase of anything else we sell (less a $50 deductible. Limit one exchange per customer). Note that warranty covers repair and return only after the DOA period. Replacement within 60 days is only guaranteed with the $50 deductible.

We also offer extended warranty packages which will increase the warranty on your used Mac to either six months or one year!
