This is a custom samurizer + blackbox running on win2k. Early posts in this thread got me thinking. I started playing with Samurizer, Coolmon, blackbox, etc. Think I stole the background from someone here too, but it changes nearly daily as I find a new black-based one. I've been using this a few weeks now, its stable.
I'm liking Blackbox, right-click-anywhere start menu is nice. Of course it has a huge game collection on the menu.
Blackbox does take some effort to get tweaked to your liking, give yourself some time. The 'start menu' can be customized a lot (see my screenshot above), but you have to include your directories and whatnot in the text files it uses to start up.
