Ordered with a 2TB internal, ordered the correct cables from Apple and installed an OWC Mercury Extreme 6 SATA3 240GB SSD and 16GB RAM. Installed the SSD (uggg pain, not for feint of heart) Installed the system, installed the Apps on the SSD, opened the terminal did a mv /path to users on SSD / path to spinning disk Did a ln -s in terminal of my users folder from the spinning disk back to the SSD Opened up sys prefs, right clicked my user and changed the user folder location to my 2TB, rebooted and viola. It's so fast I can't even describe it, my 200+GB Aperture library opens in less than 3 seconds, don't even mention Photoshop or Word, it's mind blowing. The install was truly a pain, and I work for an AASP so that's saying something but man it FLYS. I've not been so impressed with the speed of a machine ever. Totally recommended. I'd not go with the Apple SSD as it's only SATA2, so you're getting half the speed and it's about the same cost as the SATA3 offerings by OWC once you're all said and done. I thought about upgrading the spinning disk to a SATA3 model, but didn't want to screw with all the fan control mess and I truly can't imagine it being much faster. 500MB+ Read and Write from the System&Apps SSD and over 12500 on 64Bit Geekbench - that's faster than my old 8 core 3.2ghz MacPro... I'm happy. Now comes the suck of re-installing all of my Logic Pro plugins....can't wait to see how that performs.
