Also working - many thanks! Mine is an attempt at a best bang per buck set-up and the exact like of which I could not find recommended anywhere as a potential Hackintosh candidate. I was prepared to use Linux so the risk was not great. I am immensely relieved however that 10.8.4 is running smoothly.

One 3TB HD & the 120GB SSD are set up as a Fusion Drive under Mac OS (
instructions) with the other 3TB HD as an encrypted Time Machine backup drive. The encryption process took almost a day to complete but you can't be too careful after the Ed Snowden and Guardian disclosures. I am working on software that I hope to retire on - I don't want anyone stealing it.
Using built-in graphics (HD4600), the only monitor resolution currently available is 1024 x 768. The official release should fix that but as I am interested in parallel programming then I have ordered a Nvidia GT 630 rev. 2 GPU.
Now it is a little known fact that the yet-to-be released Parallela 64-core board currently holds the World record for highest performance per watt at 50 GFLOPs/W of any computing device. Parallela are currently only selling the 16-core version. The GT 630 rev.2 (older version are very different) has the record among GPUs at 27 GFLOPs/W. While the 64-core Parallela board delivers 100 GFLOPs in total, the GT 630 delivers almost 700 GFLOPs, there is space on my motherboard for two of them and with a TDP of 25W, they do not need any extra power connections (just as well as my PSU is now fully populated). I chose the Asus version with the swanky heatsink and no fan! (£54 ea).
Good luck to all experimenters everywhere!
work great now
