First off you really should have a SSD drive larger than 8GB. I’ve got the factory 8GB STEC and it took a bit of fiddling to work properly. Also get the 10.5.6 hackintosh torrent for optimal compatibility. You can use the 10.5.5 and update but if you can get the more current version do it. Also useful to have on hand an external USB DVD drive and a 8GB USB flash drive (or larger), and an imaging program to create a backup of your current setup, just in case you decide you don’t like OSX.
The installation should take 20 – 30 minutes. If you run into problems just do a Google search and find the fix. Wireless should work automatically, you might have an issue with the audio, but everything else should work once you use the DellEFI patch. Good luck!
