No. Though I don't need it, I would love to see a mid-range tower, so that those who still wanted to use OS X could, and keep all they power they had without going overboard. It's ridiculous that Apple doesn't offer a real upgradable mid-range tower option.
Yeah, as much as we all want this to happen, it's not.
I think you all will recognize this:
"Is a Mac reliable?
When you buy a PC, youre buying hardware from one company and an operating system and software from other companies. Not so with a Mac. Because Apple builds both the computer and the software that comes with it, theyre literally made for each other. So a Mac rarely freezes or crashes. And Mac OS X resists most viruses, so you can do almost anything without worrying about losing everything."
There's all of like, three pieces of hardware you can actually get third party to upgrade Macs. Hard Drives, RAM, and two Graphics Cards for the Mac Pro.
The Hard Drive and RAM requires little to no knowledge, other than a couple of minutes of Google reading to actually replace.
And there's like,
two graphics cards for the Mac Pro that are worth the upgrade. The ATI 3870's and the NVIDIA 8800 GT The Mac Pro isn't exactly the big profit product for Apple. Plus, most users won't actually take the initiative to learn how to pop open the case and pop the new graphics card in.
The point is, the way Apple is going right now, they'll never offer the fabled mid-tower that everyone longs for. That means they'd have to offer compatible drivers for every video card that's put out, and deal with the whining when they don't keep up with the video card companies on drivers. That'd really go against the whole, "...Apple builds both the computer and the software that comes with ..." They wouldn't then.
It'd cost a helluva lot of money for them to support all the new hardware that goes on the market every two months (or sometimes even less), specifically with video cards. It's a closed platform. If you want freedom with hardware, you have to stick with personal computing, plain and simple. Hehe.
end rant.
tl;dr
Apple is never going to let you choose exactly what hardware you want, and hell will freeze over before OS X is sold to run on anything like Windows. Cry more.
