Alright I'm back and i have completed the build it took a while but it is finally done:
So here it is

Motherboard: Gigabyte GA-G31M-ES2L Rev. 2
Memory: PNY 2 x 2GB PC2-6400
Processor: Intel Pentium Dual Core 2.5Ghz E5200 Processor
Video Card: NVidia Geforce 8400 GS
HD: Western Digital 500gb SATA Hard Drive

Installed: iATKOS v7 (10.5.7) with NVinject for the Graphics card
I had to buy a USB to Ethernet from apple to get internet because the rev number of my motherboard(2.x) woud be imppossible to get working (athros)

other then thoe 2 things everythimg else runs smooth and i can update from Software update just fine

So im now running iAtkos 10.5.7 -> 10.5.8 and everything works just fine!
