I have the logic board with 800mhz G4 cpu and cooler, a long with the power supply for a Quicksilver.
As well as the logic board for an iMac with a 400Mhz G3.
The logic board in the Quicksilver is very good, the one in the iMac I'm not sure about, as it doesn't want to power on until I hit the Cuda reset 3 times, tho once it's up and running it's 100% stable. I think it's the power supply that is the issue in the iMac, but I can't say for sure.
If you want all three parts for the QS $35 plus shipping. I have all the stuff to package them correct so they don't get damaged, so you won't have to pay the shipper to package them.
Just the QS logic board $20 plus shipping.
Just the G4 800 with Heat sink $10 plus shipping.
Just the QS power supply $15 plus shipping.
For the iMac logic board with G3 400 $20 plus shipping.
PM me if there is anything else you want from these Mac's, as I'm going to do a few conversions on them, and don't really need the much of the guts.
