They must have made a small batch of dual 7448 to meet demand. The only reason they are so expensive is the rarity of them along with the fact that the 7448 is the bleeding edge tech of all the G4's. It's far more tiny and advanced than other G4 chips at 90nm vs the 130-200nm size of all the others.
If I were you I would be all over that. I would love to buy that dual but will let you have it. If you ever decide to sell it just send me a private msg here and I will buy it in a heartbeat. The single like mine are rare enough but the dual are even more rare.
The bottom line is you would have the fastest G4 on earth no matter what G4 tower you put it in from the Sawtooth to the QS (no MDD compatibility). My single 7448 keeps up with dual 1.8GHz G5's so a dual 7448 will eclipse that for certain.
The Gigabit ethernet model has the same 2GB RAM capacity as the Sawtooth vs. the 1.5GB limit in the Digital Audio and QS. Over the years though I have noticed the Gigagbit PSU's are not near as reliable as the Sawtooth are. I would prefer the onboard gigabit vs. the gigabit PCI card I have to use but the PSU tradeoff made the choice for me.Let's compare ourselves to rare car collectors and enthusiast. There is no some of money that can equate to the bragging rights. Price is too steep for me but if I have cash to spare right now, I will buy it in a heart beat. It is much more enticing than let say a new macbook air. The sawtooth would be the best candidate I guess because of the maximum ram you can put into it compared with the others. Zen could correct me on this.
Mine is Gigabit Ethernet (Powermac 3.3 I guess) and the fan of the psu is making some noise/vibration any suggestion on make/model for the psu?The Gigabit ethernet model has the same 2GB RAM capacity as the Sawtooth vs. the 1.5GB limit in the Digital Audio and QS.

The DA and QS are both very reliable towers also but in my experiences the extra 512MB RAM is more of an overall system benefit than the 33MHz faster bus and AGP 4x vs 2x. OS X loves RAM as we all know so the 33% extra of 2GB vs. 1.5GB and better PSU is why I chose the Sawtooth.
To get even more life out of the great Sawtooth PSU's it's a good idea to replace the fan with a good 80mm ball bearing that blows at least 30 CFM.
