AMD 4400+ X2, 2 GB RAM, XFX 8800 GT, AMD 690 G chipset, WD 250 GB SATA II, every thing works.. PS2 keyboard also.. so no probs here.. the only thing that bothers is that the copying from DVD RW is at 2 MBps so is the writing.. and installing my HP LaserJet 1018 was really a issue as it doesn't has Mac drivers.. so i downloaded drivers form Linux printing and got it installed
Updating OS is not a big issue.. installed AMD software Update.. it downloads the software from Apple's site.. modifies it (remove mach_kernel and critical extensions, modifies GeForce.kext and NVDAResman, search and apply cpuids and decrypt encrypted files).. and update works flawlessly on Intel processors.. Intel users only need to modify DontstealMacOSX.kext.. but now they don't even need to do this..
