The G4 towers that were discounted and later discontinued at the G4's launch could hold like 4 3.5" IDE drives, a Zip drive, and an optical drive. But the G5 never managed to support more than 2 HDDs and single optical drive.

It's not underpowered at all really, it can do everything just fine - why did you think it was underpowered? I sold it for a GTX470 though.

What makes me think it was underpowered? Darn... I never have any graphs comparing a dual G5 to any recent computer lying around when I need them. Well, I'll just say this: A Zacate E350 system that peaks at 50 watts (25 watts with the right power supply) probably outperforms a dual G5 that idles at 100 watts.

They're pretty marvelous to behold. like a 3" square with a little package holding the actual CPU. On the G4's, there were cache chips - up to 1MB external L2 for the 550MHz chips on down, and up to 2MB of external L3 (L2 was integrated) for the 667Mhz and higher ones.

Sounds an awful lot like Slot 1 / Slot A, just without the plastic casing.

What's the heatpipe for? To cool the VRMs?

I finally found my CINEBENCH R10 scores of my Dual 2.7 G5 and various other computers I had at the time:

If you think that heatpipe is suspicious, you should see the back of the motherboard. There's a heatpipe snaking around that must be 18" long on back of that thing. Crazy big motherboard too. Apple must have had the CPUs and a few more things clocked to the utter limit on these machines.
And the PSU is about 12" long, 6" wide, and 2" deep, approximately. Good for 600 watts. And scarce little of that went to the anemic GPU or either of the two possible hard drives. Me thinks it was all for the CPUs. T'would explain the massive heatsinks.
7 total fans including the two fans on the PSU.

It still runs and is in daily use.

Are you also using a Delphi-sourced auto heater core as a radiator?

I was going to install Linux on the thing, but in reality its extremely underpowered by today's standards and probably also consumes a fair bit of power - especially given its low performance.
So, I gutted it.

Some other mac nut will probably know that off the top of his head. Predated the Slot 1/Slot A tomfoolery on the PC side by several years, I think.

So ummmm....where is the interface from the CPU module to the rest of the system?
