Hi khisayruou,
I'm sort of late on this plus I'm new to Mac and would like build one of this Mini/Cube.

The mod was great, but since I'm new to Mac; I have few question on the Power source.

I guess you have two power sources? One for the original Mac min and the other for the 3.5 drive (using the G4 Cube external power supply?)
Did you still hooked up with Apple Cube G4 Board DC to DC to drop the 28 V to 12V, 3V and 3.3V?

The reason I'm asking is that I'm going one step further to add muitliple HDs (Possibaly 4 2.5 SATA HDs, might go into SSD later) trying to set up a RAID system with a HPM (Hardware port multipler, which will also need power to run!)

So, in summary on your system:
1) you have mac mini power supply hooked up to the mini which powered the Motherboard in mini, and the large CPU fan?

2) The second power supply powered the 3.5 SATA HD and the DVD drive?

3) Do you have the "Apple Cube G4 Board DC to DC" attached to the second power supply? and this power supply is for the G4 Cube unit?

4) I assume that the sensor button is hooked up to both power supplies?

And finally, what are the Coxial connetors for? and what are they hooked up to?



Thanks!

Hey hsus2k! I was surprised to see this thread back!

Yea, it uses two power sources. One is the original external brick from the mac mini and the other is a power supply pulled from a 3.5" external enclosure. The mod does not use any power sources from the original g4 cube.

Its only hooked up to the external power source

My original design was to modify and build in a tv tuner but then elgato came out with a small external device so I scratched the idea.

Happy modding, your mod sounds sweet. Im sure it will run much cooler as well. If you need more power you can always draw it from the USB ports.

khisayruou,

Thank you for your prompt answers, now makes a lot clear to me. I still prefer one on/off switch. (for dual power supplies)

I know I had pulled this old thread from long ago, but the G4 Cube looks fantastic! Especially your Mod with the Mini! I love it.

If my internal Raid system work (Runing to issues right now) I'll need to hide all those HDs and additional parts (which I know they will not fit into the original Mini) So, I figure the G4 Cube Case is the Best way to go, instead of hook up to a External RAID case.

Thank you for your help!
