I picked up an Apple Mini Mac for $599 and Fry's Electronics today. It was the low end unit with plans to swap out some of the guts for a mega upgrade that would be an unavailable configuration from Apple.
For those with access to Yonah chips or prefer to purchase from an online retailer but did not have a platform to run it on, this is very cool interim machine to check out.
The motherboard is an Intel Napa. It uses SODIMM and supports up to 2GB of DDR2 ram. It also run in dual channel mode as long as you keep DIMM's matched.
You have no ability to manually adjust memory timing but it will uphold SPD information like a champ.
I did some research into breaking the Apple spirit and getting windows operational and I know it will be possible based on depth of Apple protection.
The case is held together with about 30 plastic clips on the bottom. These clips are pretty tough to get worked apart without hurting the case appearance. The most common method for case removal is a putty knife but this will leave bad scars on the case. I would suggest researching the wire method for case opening. It is very clean and takes the same amount of time.
Once you get the case open it will take you a few minutes of spinning the thing around to figure out how to take it apart. Look for four black screws at the base of the black plastic CD/HD bracket. The four holes are show in this image at all four corners.
You will see a lot of little black connectors at the rear of the CDROM, leave these alone as they can stay on and the whole assembly comes out.
There is two antennas mounted to the top of the CDROM, carefully lift on the smaller one and it pops off, the larger has two clips from the underside that squeeze together and it will lift off very easily.
Once those two parts are clear there is the one more connector at the front of the CDROM you need to be careful with when you lift the drives out. Undo that clip and the drives are free.
You should be looking at the system board, the north bridge and CPU covered by separate heat sinks and the two ram slots. You will need to remove the motherboard to remove the CPU heat sink. The screw is located at the front corner with a taller spacer screw with hex top, it has a chrome finish and should be easy to spot.
Carefully clear the front edge and pull it out. Nothing on the back panel prevents the motherboard from being removed, just be careful of metal shielding.
The south bridge is located on the backside of the motherboard and has a thick piece of thermal interface material stuck to the bottom side of the case, remember this when pulling out or reinstalling the motherboard not to mess it up.
Once the motherboard is out, flip it over and locate the plastic tabs that hold down the CPU bracket. Squeeze them and it will pop off. I highly suggest using one hand to hold heat sink level as it can and will flop to one side with possible damage to core edges. The same goes for reassembly. You will also see a small connector for a thermal diode attached to the underside of the heat sink once you have it loose, remove the clip if you want to remove it completely.
With the CPU exposed, clean off the thermal interface material. It is black in color and feels like tar.
I picked the Core Solo Mac version to show that all models are the same, it would just need a CPU swap. Like all Intel motherboards, memory selection is not an issue as this will accept pretty much any speed or timing SODIMM you put in it. I will be testing with Samsung and 1GB modules as well.
I am very happy to see high definition audio onboard as well as all the other features available on this low end model.
Two more upgrades may be planned, the HD to 200+ GB and DVD-RW drives are a bit less than optimal but will surely get the job done at the current price point of $599
I have a new camera that will be here Monday with an uber macro lens. I will update with PLL and finer board shots.
