First of all, I'd like to join everyone and thanks Zephyroth for all the time he puts in this project. This release is awesome.

I installed 10.5.2, and everything seem good so far.

My specs:
OS X: Leopard 10.5.2 R1 by Zephyroth
Board: EVGA 131-K8-NF44-AX NF4
Memory: 2GB OCZ Platinum
CPU: AMD Athlon 64 X2 4800+ Toledo
Graphic: MSI GeForce 7800 GTX 256 (now working with NVInject 0.2.1/10.5.2 kext also QE/CI)
Integrated Audio: AC97
HD: WD 160GB
DVD - IDE CW-8123-C Slot Drive from iMac

My install options:
MBR formatted in DISK UTILITY, Kernel 9.2.0, EFI (MBR), Forcedeth.kext, NVidia+NVinject, Azelia Audio (removed), NForce Chipset

The first time I used the AC97 but it didn't worked, so I tried Azelia, and it didn't worked either. From there I just deleted Azelia, and use the ALC850-Install.zip floating around, and this time it kicked in .

BTW, I tried to use my Pioneer SATA DVD drive first to install from the DVD but got a "Waiting for root device" stuck. Using a IDE slot drive picked from a broken iMac here worked like a charm (just a bit noisy).
