How can I create a special custom made 100% dust free container for computing equipment?

All my life I have dreamt of owning a supercomputer, and over the last few days I have been reading up on some of the latest hardware. I have been comparing the top of the range products to the first computer I had that I actually found impressive. Yes, I was actually once very impressed by a 166mhz CPU and an 80mb hard drive. Suffice it to say that the technology on sale now is magical by comparison. Processors with six cores, motherboards capable of holding four processors, 3tb hard drives, and all kinds of other amazing goodies.

In a years time the technology available will be even better, and if I start saving money now, next year I can treat my self to something really special. But it looks like the investment will be comparable with that of buying a new car. If I really am going to spend that kind of money, I don’t even want a single speck of dust getting in to it. Dust can make computers run less efficiently, or even totally destroy them. The oldest PC that I have here at home is about 2 years old, and is totally full of dust, I can’t let that happen to my dream computer. There are cleaning methods, but they can do more damage than good.

I will need to build a custom made container that houses the computer. The container will need to keep the computing equipment totally dust free, as well as cool and well ventilated. It will need to have access points for inserting DVDs and CDs, as well as exit points for cables. It will also need transparent points so I can see inside, or small cameras inside so I can see. Then you have things such as USB hubs that will need to be on it, and slots for cards and things.

Obviously I will have a full year to design the container, and while I do have engineering experience, I could really use some advice. Not only on making it functional, but real bad ass looking too.

So, how would you create a container like this? What materials could I use? What cooling systems are there that I could use? Etc…
