Porn Collecting - What tools are best?

BenEnglishAtHome writes: What tools do you need to best build a porn collection? It's a geek in-joke that there are serious porn collectors in our ranks but it's also true. Anybody can get a usenet server account and try to grab all the binaries in the alt.* hierarchy or use a spidering program and grab a million files off the web. However, it takes serious tools and commitment to handle the resulting 100,000-file directories. How would you set up your ideal porn-collection system (OS, file system, hardware minimums, setup tuning tips)? What programs make it easy to edit/sort/file/view millions of media files? How do you identify and toss the dross that inevitably makes up 99% of what you download? Share, brother geeks, and make life better for us all.
