I didn't have it five minutes and I already took it apart.
1 - 2 horas
I bought a new Quad 2.6 i7 Mac Mini and I wanted to upgrade it as soon as possible.
Really well. The supplied teardown instructions were more than adequate. After about 20 minutes of tinkering, my new mini was roaring into action.
I'm no stranger to repairing Macs, but the Mac Mini is especially complex inside. There are many small delicate parts that you have to pay close attention to. The guide and supplied tools are great, but don't try to skip steps or force anything.
