Used G5 iMacs - 20 in.

Home » Pre-Owned / Used Macintosh Computers » Used G5 iMacs - 20 in.

In addition to our 90 day used Mac warranty, when you buy a certified used iMac 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 Macbooks, used 17" MacBook Pros, used iMacs, used Mac minis or our other models of used Macs in the links to the left.

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.
