Damaged G4 Cube logic board

[p4ush]

Long time lurker here.. not many posts from me but would appreciate any help..

I have a spare G4 Cube logic board which I bought a long time ago, that unfortunately got damaged in transit.

Someone had likely gutted a Cube to “make something modern of it” and sold all of the innards.

To my naked eye, I can see four bits of damage caused by the optical drive rubbing against it, thanks to bad packaging.

Two components were ripped off, the IDE connector smashed up and the CPU socket has a couple of iffy looking pins.

I’ve no idea if the board worked in the first place, but I’ve nothing to lose trying to see if I can get it up and working again.

I won’t lie - my electrical knowledge isn’t top spec. I think I can easily find a replacement inductor but what I assume is a MOSFET might be a little more difficult.

Any thoughts or input would be much appreciated.

I’m currently away from my Cube, or I’d check its motherboard for you, but your general assumptions are correct.

The inductor L9 says 221 on top, which means it’s probably 220uH. If you can find a 220uH inductor of similar footprint and physical dimension, it should work just fine.

The chip U15 says 9407 on top, and the footprint matches that of other SOIC-8 MOSFETs, so I googled “9407 mosfet” and found that the NDS9407 is a common P-channel MOSFET in this package size.

The IDE socket doesn’t look too bad in the pictures you attached, but if it’s bent to the point that you can’t bend pins back, you may want to consider selectively desoldering pins and then sliding new 0.1” header pins into their place. If that’s too messy, replacing the connector entirely will be most easily done by removing the plastic shroud from the pins and desoldering them one-by-one. Then you get to spend some quality time with a solder sucker cleaning the through-holes…

For the CPU connector, all I can say is good luck and get yourself some nice tweezers…
