What type of Server should I use to host an Adult Video Website?

I currently have a Windows 2003 Server, with IIS 6 and SQL Server 2005. I want to be able to embed videos using a script from a company such as AVS. The prob is that most of them seem to use MySQL and PHP as preference. Is it possible for me to add the php scripts to my windows server. Or should I convert it over to a linux box? Thanks.
