PS2 mods(not a chip)?

[Kadis]

I'm just really board right now and I was thinking about how people do computer mods. Is it posible to do things like this to a ps2? I'd like to put a small neon tube inside of mine, however I don't know where to make the connections. Can anyone give me any info on how I can do this?

Thanks,
Josh

P.S.: Yea I know it's lame, but it'd give me something to do for a bit...
