I have no idea how you came across that one first. Network cards are a
commodity and start in the single-Euro (so probably also dollar) range these
days. Intel cards start in the 20–30 range:

My PC is over 7 years old now and I’ve always been unsing its internal
ethernet port. Most consumer boards use Realtek chips, and so does mine,
because they are a little cheaper than Intel’s counterparts. Enthusiasts and
power users like Intel more because it does more in hardware and offers more
features, whereas the realtek driver puts some load on the CPU, AFAIK. But
in my view, that is counting crumbs, as we say in Germany. I’ve never had
bandwidth problems and always had the full 1 Gb to my NAS. For us normal
home user folk, it won’t make a difference, IMHO. (Except if you are a
purist and care about code quality; I think there were niggles with
Realtek’s code a longer while back.)

That’s the one veryone uses. I actually have two of those installed; one
one-board, the other one as a PCIe card that I got from my old employer.

Sure you can. Are you a hardcore gamer? Does your card consume 100s of W all
the time? Usually the GPU is the top-most card except for cases that hold
the board upside-down (meaning hot air rises away).

> Can I plug these types of cards into the larger slots?

Yes. Speeds are downward-compatible. One PCIe 2.0 lane is fast enough for 1
Gb.

If you change the filter in the link I gave you at the top, you can also
look for PCI-based cards (unselect PCIe first). It’s possible that PCIe,
though a faster interface, may be more frugal these days. When PCI was
invented, power saving was not an issue.

Why should they? A hunch? The only real benefit is you can easliy swap them
in case of failure. But as long as you have it and it works – why not give
it a try with what you have before you spend more for something you may not
even need?
