Inside this terrible nightmare, I was lucky enough to get my zombie HDDs back to life again - Thank you so much Alsoft! -  DiskWarrior ran continiously but effectively over my external FW 160Gb Samsung hard disk for almost 48 hrs. < sigh >

I took the suggestion of another Cube user, who thought it could be the hdd clock (ATA 100), so I've downclocked it to 66 using a friend's PC. (There's a utility at Seagate website but it is windows only). Didn't work out.

So I also took the chance of saying 'see you soon' to my friend one week later and I've put the CPU+SuperDrive package in his rucksack back to USA, as I didn't want a SD in my Cube with the original 450MHz CPU. Don't know if PL 'accepted' the problem, but my money is there for me to pick up whatever I want. But I for sure don't want any other PL CPU upgrade.

"The Cube upgrade supports fan less operation at 1.6GHz, and 1.7GHz+ operation with the addition of a low speed fan." Giga uses the latest 7447A Freescale chips, and they claim to be the coolest ones out there for Cubes.

"The Encore/ST supports hard disk and display sleep in all compatible PowerMac G4 computers. In some configurations, deep sleep may not be supported." Sonnet uses the 7457 chips, same that were used by PL for their 1.35GHz chips... that gives me the creeps.

I wouldn't buy a PowerLogix product if they paid me. I have been lied to 
, made to wait without any reason and lost about 300 $ in the deal. 
Installing and using a PL product in a Cube or any other precious Mac is 
like playing hardware Russian roulette.

Sorry to read about your problem btw.
