Audio guy here… I honestly don’t know of any PCI cards. The main problem is the connecter for these types of mics is too big to fit on a card like that. The Focusrite is awesome bang for your buck. I would try to hide it behind your desk. There’s no reason really for you to keep it on top.
If you’re that concerned about having an extra piece of hardware on your desk, you could try something like a high quality USB mic. I like the Shure MV7. But there are a ton like them if you search for mics made for podcasting.
It’s both.
