Olin Coles from BenchmarkReviews has written an editorial about the future of computer cases, you can read it over here.
I can remember the lead-sleds that rolled with a curb weight similar to moving vans, and it reminds me of modern-day desktop computer cases. Originally, giant-sized computer cases painted in beige were once the de facto standard for system builders wanting to construct their own IBM clone personal computer from separate components. I believed this horrible trend would phase itself out around the turn of the century, but when Y2K came and went and there was still significant demand for large full-tower cases I knew something was wrong. The more things change in this industry, the more they seem to remain the same. Now more than ten years later, we're still building our PCs with the same heft as an Oldsmobile Toronado.
