The Lian Li Cases are very solid, and built for complete luxury (if that is possible in computer cases). I would recommend keeping your current case, or finding a bigger modle if you need more space.
In that case, I would go with whichever one you can find the best deal, ie- least expensive. The Lian Li case offers more features and more internal drives, and at newegg.com, it is cheaper than the Coolmaster.
I bought my Lian Li <A HREF="http://www.mpcparts.com" target="_new"><b>here</b></A>. It was the cheapest
place I could find and the service was excellent.
