the plastic top is definitely the weak link on the FT02. the clip feels very tight to me and sometimes i feel like i'm almost breaking the clip just to take the top off. HOWEVER, even IF the clip breaks off after 10 years of usage, (yah i definately think the plastic will last at least that long) all you have to do is mod some magnets or some velcro tape onto the top and you'll be back in business.
also, you are severely underestimating the quality of the FT02 if you are only thinking of keeping the case for 6 years:D I wouldn't be surprised if the FT02 is the last ATX case you buy
