My current 5,1 hexcore is satisfactory in terms of GPU and CPU power for my productivity needs. I have tons of external storage purchased on the cheap--something the new Mac Pro will be unable to accomplish. With this aspect of my computing needs covered, my gaming needs are still left wanting. I therefore decided to go the dual computer route, being as how I had a PC case anyway I was using as my external RAID. I couldn't be happier, and it was a fraction of the cost with markedly more upgradability than the New Mac Pro. PC: -Haswell 4770K i7 -EVGA Superclocked GTX780 w/ACX cooler -16GB RAM -128GB super-fast SSD setup as a "Fusion Drive" (SSD Cache) through intel SRT -1TB WD Caviar Blue -Asus Z87 Pro (no thunderbolt, OMG NO!) -Corsair H60 CPU watercooler -Corsair HX750 PSU -Dual Link DVI KVM (For when I get a 1440p monitor someday). -No optical drive (I have an extra optical I hooked up externally via eSATA and an extra power connector I used to install Windows 7) It also has Two x 5 hard drive backplanes and 2 port multipliers I'm still using as my RAID for my Mac (this aspect has an external PSU). This is just for storage, not for speed. I have all my internal HD bays and the optical bays full in my Mac Pro. Mac Pro -3.33ghz Hex-Core Xeon -16GB 1333mhz DDR3 -SSD boot drive + 3 internal platter drives -Radeon 5870 -Gigabyte "Windforce" Geforce GTX670 *Highly recommended! -Rosewill 500Watt 80 PLUS certified External PSU for GTX670 -BluRay reader & DVD burner -4 port eSATA II controller -eSATA RAID inside above PC case - 8 drives, one RAID 10, one RAID 1, one TM backup for all other data (total redundancy) Monitor: ASUS VG278H 27" 120hz x 1980p (3D) & 24" 1980p Sound: Sony receiver with 5-disc DVD changer (what can I say? it has good sound) Pics: What it looks like from the front (where's the PC? It's being sneaky). Keep in mind the PC is QUIETER than my Mac Pro even on full load (with the desk compartment closed) Here is the compartment. The drawer has to be removed before anything can be tinkered with, but this was the best of a short list of options (like getting rid of the drawer and just using hinges). I built a remote for my KVM (additional buttons for volume control/mute on my receiver): Just like christmas! Desk compartment. Top left is a 450Watt PSU for the desk compartment fans AND the RAID inside the PC case. The bottom has a 200mm fan and two 120mm fans, in the back there are two additional 120mm fans that go up to 120CFU each. I use a fan controller for the top fans. Ambient temperatures in this compartment are about 3 degrees C above room temp under full load!! Here's a better view of the fans in the base. Those metal things? Drawer slides! The case weighs 50 pounds, these slides handle them easily (had to reinforce the desk). I had to build some of my own power cables to rig the external PSU to the two backplanes Finished internal component placement (whew!). There is a 130CFU sidefan. Ambient temperatures remain below 35 degrees C at max load (GPU below 70, CPU below 50)!! Pretty darn heavy. The cables on the top are external power for the hard drives. Aftermarket fan and temperature monitor for the compartment View from side, KVM is mounted where I can barely see the indicator from where I sit. I never need to hit the switch button on the box because I built a remote (see above). I have a retro-fitted 120mm fan in the Mac Pro with a fan controller I built myself. The back is not so pretty (but who cares). It's been consolidated a lot since this pic was taken, the router was remounted in a better way too. This is probably made worse by the external PSU I use for my GTX670 in my MP. I consolidated a few of the cables since then, all this is basically invisible from the front.
