Hi borce-razor,
We, the hackintosh community, have reached a stage where anything is possible (still trying to digest how f*cking AWESOME SL runs on my new Dell Mini 9 - unbelievable! )
that being said, you will certainly have a perfectly functional laptop running SL.
You will always have some quirks at first, say... no internal "mic in" or... no sleep.. first boot with crappy gfx.. these three are quite common. But everything is fixable nowawdays, some tweaking is a real pain and quite scary if you've never done it before. Nothing is HW dangerous, but take this with a big grain of salt... But being on a laptop you are safe (talking mainly about desktop speedstep issues where overheating might occur, or if you loose your mind and decide to flash your BIOS to mimic a Macbook)
Do no be scared to try, do NOT have love for any Data you did not backup!
I am have zero ATI knowledge, nvidia alone keeps me too busy to follow. But lately, as of 10.5.7, the only ATI's I've read not to work are from people who did not yet understand how to properly "wake it up". I do not know of any particular model which is more or less troublesome... you might not have hdmi out, or vga out... but all things are fixable to the degree of your computer skill nerdiness.
Intel wireless (amog few other HW here and there) is absolutely NOT going to work (except the ood model which works more or less) - Havind a broadcom is brilliant, especially if its the 1390 or 1490 model. There are loads of Broadcom kexts (drivers), and thant to the Dell Mini family, you will certainly, eventually, wake it up, if not right out of the box!
In any case, being pci-e, will cost 15-20 + a scredriver and 2 minutes of your time to get native airport support.
I would suggest you buy a blank drive to experiment on, anything goes wrong, just re-format and restart, at the end of the day it did not work, pop in your current HD an keep surfing, of keep you legal Windows or favourite game whatever...
I play GTA 4 off e-sata on Vista 32
DO NOT try to dual boot at first. Learn the procedure, be sure to install proper, test run the system for a week, dont go all download crazy at first, clone your drive with Carbon Copy Cloner (amazing app and free) to a backup so anything goes wrong, just restore back. Work perfect, unlike Windows.
THEN you try dual booting!
Avoid Western Digital hard drives as MANY models do not work, this is official Apple issue, the website has the listed models, I had problems, mormegil had problems, but one dude over at my SL thread had issues but got it working... I'd REALLY avoid it!
Also, go for Snow!! not "old" Leo

- much better.
DO IT !!
