We've had these towers since the G5 era...they are big as refrigerators.
Smallest refrigerator I've ever seen.
Many (many) in the mac community have been hoping for a smaller, streamlined tower for a long time.
Do you have any evidence for this assertion?
You remember the old PowerMac 9500 with SIX PCI slots -- even that tower wasn't nearly as big at the Mac Pro tower.
You're comparing a single CPU machine from over a decade ago with a 2009 computer? With two Xeons and an EATX motherboard? Do you expect to fit a pair of Xeons and all the associated circuitry on a tiny motherboard? The vast majority of proper workstation/server-grade motherboards are EATX. That's 12x13 inches. Add the space needed for a 1000 watt PSU and so on and there you go: one Mac Pro tower. Compared to some of the PC full towers I've owned, the Mac Pro is tiny.
THe major advantage to the Mac Pro tower size it's ability to hold 4 internal drives.
It's = it is. "THe [sic] major advantage to the Mac Pro tower size it is ability to hold 4 internal drives" doesn't make any sense.
I am sorry, but I think the tower is just a bulky monster of metal and it's just way too big and way too heavy. Some might like that, but personally I think it's time to size down to something more liftable with less impact on the deskspace (or space below).
What happened to the many (many) people clamouring for a smaller Mac Pro tower? Have they all gone home or been abducted by aliens?
Maybe when Apple replaces HD technology with SSD we will see the sizes of the tower shrink.
Yes, because hard drives take up so much space. If you take the side off your Mac Pro, it's the motherboard and the cooling stuff that dictate the size of the thing for the most part.
The current Xeons with the heatsinks take up quite a bit of space as well.
Would Intel Atoms be a better fit, perhaps? This is a workstation, not some cheapo piece of junk. It's supposed to be the most powerful Mac you can get. If you compromise on CPUs, then you compromise on power.
The tower is simply a mammoth of aluminum, and it's heavy. Really heavy.
How often do you lift up/move your Mac Pro? I must have moved mine about three times this year, to clean underneath it and to upgrade it (and that's only because I bought a GPU and a replacement hard drive this year). Oh, and I redecorated. If the Mac Pro's weight is an issue, perhaps you should go to the gym.
Sorry if this post sounds like a pointless vent, but I felt like it was an issue worth addressing.
To call your post a "pointless vent" is an insult to other pointless vents. And, once more, you revert to the first person singular. I'd call the missing persons helpline if I were you. All these Mac Pro owners gone missing. Perhaps Steve has had them "taken care of".
