9x6 is not a whole lot of space... If this is going to be a display area, you'll do well to get half a dozen in there comfortably. If you set up a rack system, then you're golden for breeding, as well... Somebody wants to see your prize baby,m you can always open up that drawer and pull him/her out.
We do things a little differently, since our snakes are as much a part of our lives as any other animals. One rather large terrarium housing our grey rat snake is right next to the idiot box, and we spend more time watching her than we do watching television. Near the kitchen is a stack of three smaller display tanks. The only ones which aren's on display is our less active (but more frequently fed, as they are babies) macklot's... They're in tupperwares, for now, but, with our moving to a new home before too terribly long, they'll have new homes too... 
We don't really have a reptile room; we just have critters scattered throughout our home, so that we can watch and enjoy no matter where we are... Now, I just gotta get a web cam on them...
