exactly. i wasn't advocating building one yourself, just saying that's the only way you'd find a cheaper workstation with similiar specs to the mac pro.
No, I know. It wasn't an attack.

I found an opportunity to explain why DIY doesn't work for me, while at the same time highlighting what used to be my pride and joy. Believe me, if OSX was available to the masses, I'd build myself one hell of a machine, and still be able to use some of the existing components.
I started building PC's back in 2002. Built quite a few, mostly for friends and family. My own personal rig saw many, many, many rebuilds. New hardware came out, decided to try watercooling, went to a bigger case (Stacker), changed platforms (Intel to AMD), got a bigger radiator, etc.. etc.. It was fun while it lasted, and my current setup has been running strong for 2 1/2 years. I guess I've grown out of it.
My biggest sticking point with the Mac Pro is the video card. Because we can use BootCamp, I want to have my cake and eat it too. I want a good gaming machine for the times I play (every so often), want to retain my Windows-specific apps, and have OSX.........all in one box. Aside from the clutter of having multiple machines, its fiscally unsound to throw all that money down the drain (or in this case, the wall socket), and it's certainly not being "green".
I've waited a long time for a Mac Pro update because, like I'm sure everyone can relate to, I said "Oh, I'll wait for MacWorld. Something's sure to be updated then". And then I said "I'll wait for WWDC 2007. Surely they'll update it at WWDC", and of course it didn't happen. So I make due in the meantime by getting my OSX fix with the Powerbook and the gaming/multi-monitor/general usage fix with the PC. So, I can still hold out a bit longer, but that doesn't make the waiting any easier.
