The original Silverstone FT01 Forstress is a mid tower case with three separate drive cage cages. The middle and/or bottom drive cages are easily removeable to accomodate extra long video cards like the 5970.
Lets be honest Its time to get creative or stop whining
Either use your brain, buy a aluminium case and put some cushions around your case or whatever to protect it in the car.
OR stop whining about your case being "really heavy" it must weight about 20KG big wooop
Thanks for the informative and helpful post.
I'd rather spend money and get a tried and true, unmodified case then waste time tinkering around with something. And I have to carry the case down the stairs of my three floor apartment once a week to transport to my home in La Canada. I wasn't being literal about the "few bumps," the highway between SD and LA is ~120 miles, and I feel uncomfortable transporting $3000 worth of components in a flimsy aluminum box.
