Lol, if you think that's bad you should of seen it a month ago before I cleaned it.
I could of made a dust bunny shirt from all the times that I've cleaned it.

I definitely need some sort of filtering, either for my room or my pc.
It really sucks having a transparent case where you can see all that.
I don't recommend acrylic...

If I can get enough lego's together I'll build one out of those.
Either that or find a decent steal case that has alot of 5&1/4 drive bays.
