I used the tonymac method, its brilliant and easy, loaded most of my drivers and kernels at setup, so pretty much everything was ready to go, my system is stable so far, havent crashed once, although it does sometimes not start up first boot, it will take a restart but after that it runs fine, i suppose it just depends on your specs and system load, aswell as custom kernels and how well your processor can cope with reading it differently... if that makes sense ?
im running it on a modified dell vostro 420 tower with a quad core, no problems there, really want to try lion though, haven't got around to it yet, might buy it this half term. whats it like ? any major changes ???
