I think i blog about one of the mac-alike site before ( in fact google mac alike and my blog will be on top ) , but i just found another when reading of my rss feed, meet The iFizzle – Impossibly Kick-Ass
if compare this site to flyakiteOSX , no doubt that this site looks better, with more feature, but flyakiteOSX focus not really on the mac-alike design, its more on their software package that make windows XP looks like mac. any the creator of this site is looking for donation to buy a real mac, if he get enough money to buy one, he will release this site as public service, so support him if you like the design.
the site closed, i wanted to download it, although, the vista is pretty mac-like, but too expensive and it requires a lot of change for the pc.
