Best Computer Case?

It's hard to argue that Apple computers are not beautifully built. Just try to open a MacPro, touch the materials, see how everything fits perfectly... pictures really can't explain and ...uh I am getting slightly aroused. But there is more to life than Apple, and sometimes you need a PC to run a variety of software on other operating systems.
While London School of Sound has an excellent Synergy PC which is currently running Pro Tools 8, Reaper (version 3.05 is out), and every plugin you can possibly imagine, for myself I prefer to build my own machines.
And before I even start thinking about what will go inside, my first concern is always the case: will I find something that works, is quiet, well built, has easy access for when you need to change a hard drive, good air-flow, and doesn't look like a sad horrible PC? Well, here is a couple of contenders.
First of all something which is indeed powerful and quiet, and in terms of functionality probably the best enclosure I have seen in my whole life, if you need a computer dedicated to professional audio/video. The looks however are still somewhat uninspiring, and I inclined to look for something a bit more... well, have a look at this. Most people will complain that it's huge but that's part of the reason why I like it, easy to build, lots of airflow inside, nice slik metal feel to it and despite its size and weight very easy to move around thank to those handles (possible the only criticism I can make to the case of a MacPro where the handles will cut your hands if you carry one for more than three metres.
Alternatively the only solution is to do what this crazy guy did (and I might actually do one, watch this space).

> update: I ended up buying the CoolerMaster Cosmos-S – it ain't no mac. Still very plasticky, and tricky to work with. It's hard to believe that in twenty years of making PC cases no one in the whole world has ever managed to get a really good one. One of these days I will have to get in to AutoCAD and put together one.
