G4 Power Mac Towers

Home » Used Macs » G4 Power Mac Towers

In addition to our 90 day used Mac warranty, when you buy a certified used Power Mac from PowerMax, you get two additional guarantees: First, if your used Mac arrives and isn't working as it should, we'll pick it up and replace it at our expense (some conditions apply).

Second, if at any time during the first 90 days of the purchase of a pre-owned Mac, you wish to trade in your Mac, we'll guarantee you the FULL purchase price value you paid toward the purchase of anything else we sell! Check out our FAQ on used Macs here.

You may also want to check out our selection of used iMacs, used G5 towers, or a used Mac mini.

Also, if you're a volume buyer (five or more units), be sure to call one of our PowerMax consultants, who will happily work up a special quote with quantity pricing.
