Leads for the capacitor are exposed, not good ... a hair floating in the air, or some other thing could bridge it and schwammy! Most run open boxes, so that the cap leads are exposed is not good. It might be effective for OC power spikes for the card attached, but generally, I just think having a Capacitor with exposed leads for generally open box systems is not good. Lots of open boxers are learning that spiders, and baby spiders, etc ... love the warmth of open boxes as they attract insects as well. One invisible thread of spider web, and zappage. I like the concept, but not the implementation.
You could say that about anything inside a computer, especially any risers because of the contacts and pins that are so close together.
