I'm looking at getting the coolermaster stacker case, and I think the big 300mm vent on the side might make for a perfect fit for a circular window kit I've seen (not to mention being a rather easy and minor mod to make). Question is, are they worth it? Or should I be more looking for the whole way and going a full side window? (I'm planning to put in a couple of UV cold cathodes along with maybe a blue and red one for light transition - being a big case it should work, I hope)
