Thanks for that Directron link. Had never heard of them, but, yup, huge selection and, unlike so many sites, good product descriptions.

I now have 2 of the Lian-Li PC-60USB cases. Way too much money, but worth it (Huh????)

I haven't seen a completely transparent case yet, but side windows seem to be all the rage. This place sells a kit to let you cut and fit a window on any case -- and they even sell neon lights if you want to stare at an illuminated motherboard!
