Having just replaced the 11 1500uf Jackons on my Abit BE6-II, I noted the difference in size between these and the Panasonic FCs that I put in. It led me to thinking about why it's a problem to get 8mm caps in 1500uf, 6.3V. The third most important parameter when choosing capacitors in a design is of course the current rating. As CPUs have got faster, and the core is pulling out more big current pulses from the reservoir caps, then they will demand more current capacity from the caps. I haven't checked the current rating of the Jackons compared to the Panasonics, but maybe Panasonic are more conservative about their ratings than Jackon and others, and that's why their caps are bigger?
I had about 5 of the 11 on the board with bulging tops and bottoms, though no real leakage. Some of the remainder had bottoms bulging. The Vcore, which was noisy, is now rock solid, so what the real capacitance left in the old Jackons was I don't know! Not much I would suspect..
