Doomguy - First, there are two different types of GeForce / AGP problems.
The first is a power problem which affected the GF cards (not the GF2 cards). Is was related to the way some MB makers delivered power to the AGP slot. Because the GF was so close to the limit of what the AGP slot could provide, some MB's could not handle it. Note that some older LX MB's have problems with many other videocards, but the GF problem was much more widespread than that.
3dfx at least removed that as an issue by not relying on the AGP slot to provided power.
The second problem is using the AGP slot at more than 1X speed. This seems to be a problem with AMD and VIA chipsets. The drivers have had a work around for a while (they disable the AGP features without warning or informing the user).
It could be argued that these chipsets are not following the "spec", but they do make up a pretty high percentage of the MB population. It would have been good if NVIDIA had worked with them to ensure their products could work as advertised. I haven't heard of ATi having this problem (3dfx doesn't use all the AGP features so this isn't as much an issue for them although there was a rumour that the reason for the extra V5 5500 delay was to ensure it worked properly on Via-based motherboards).
BenSkyWalker - First - congrats on the newborn. I'm surprised you're awake enough to post these days. Mrs Michael and I went to the beach with our 3 year old yesterday, kids are great.
Second - I've looked to see if I could find a specs document for ATX cases. I have a couple of case styles and it would fit in all of them (one, a mini-tower, I might have to sacrifice one 3 1/2" bay but it is a $30 case and I doubt that someone buying a $600 video card would be using such a cheap case).
All the size "issues" that I've read about seem to be drive cage related. My very loaded mid-tower has plenty of room for a V5 6K (I'm not intending on buying one).
Michael
ps - regular as clockwork, as soon as the V5 6K is mentioned the same people always jump in and start bashing it.
