$3000 budget for Scrypt mining rig...help me spec it out

[jdndndndx]

I am a computer programmer, but I haven't built my own machine in 10 years. I see that people are moving to milk crate/PVC pipe cases and am not even sure where to start or why I would want to do that. I know that I would want 4 - 5 GPUs, but I have no idea what type I should get.
