They say the total length of the card is about 208mm, that would make it able to fit in a TU100 or a CM 110. Reviews arn't half bad either.
Yes, I've seen that And according to @ccRicers, it is even shorter without the shroud, 191mm to be exact. It can fit nearly anywhere. I am in the planning phase of putting one into a LianLi PC-Q12, and from everything I've tested and measured, it will fit nicely.
I retired my VX550W. It's served my needs very well since '08 but being non-modular and only rated at 80 plus, it's not the ideal choice for an SFF build.
