Quad-core 2.66GHz, 4gb, 500gb, single GeForce 7300 GT, 23" display, 16x superdrive, bluetooth module, wireless kb/mouse - $4314.
Drop that to 2gb/250gb, and it's $3785.
Or make it a 3.0GHz octo-core, and it's $5812.
All of those are, while very expensive, within the realm of reason. I could, in theory, afford them (even with the siding project we've just gotten financing approval on)
Tho, the 'dream machine' (as it were) is still outrageous. octo-core, 16gb, dual 750gb, dual 23" monitors is $11,279. Another two 750gb drives are $500 per, and switching up to 30" displays is $900 per plus I'd need another video card ($150). Whee.
Oh, and I just noticed, there's a 3.0ghz quad-core 2gb/250gb mac pro refurb available for $3299.
I should stop looking at this now.
