> Is that also true for unmagnetized neodymium?

Yup! For almost all magnetic materials the permeability will be the same whether or not they are "set". One exception is in extremely high quality transformer steel- this stuff is specially rolled so its anisotropic. It's flattened into strips, which squishes its crystal structure into very long, thin needles. The atoms inside the needles can flip around easily, but they can only line up in the direction of the needles. They swap back and forth very, very easily, but they can't do the same for side-to-side fields. Once they're set they have great permeability in one direction and mediocre permeability in other directions.

Neodymium magnets have essentially the same structure- very long needle-like magnetic sections, but they're extremely resistant to being turned around. Even the individual neodymium atoms (which are the field-carrying component) are essentially locked in place by their chemical bonds. Iron atoms on the other hand can rotate almost freely; that property is the same one that makes iron (and metals in general) ductile, since the atoms can move with respect to each other.

One of the most important parts of making neodymium magnets is actually an annealing phase, where the magnet is heated for a very long time to line up the magnetic sections. This also has to be done in a low-oxygen atmosphere, and is one of the big reasons neodymium magnets are expensive. Without annealing the magnetic fields cancel each other out to a large degree, so an un-set magnet can have an even lower permeability than a set magnet- but a set neodymium magnet will have almost zero permeability in directions other than the magnetic field.

> I bought some neodymium magnets several years ago to play with and they are amazingly strong.

I love them! Pick up some ferrofluid too, but be careful as it will stain anything practically permanently. The color comes from nanoscale (<10 nm) iron particles that will just nestle into cracks on anything less porous than glass, which is essentially everything. Ferrofluid got me the brainwave of understanding why iron particles line up the way they do.

Another cool thing is that we're finding requirements for even stronger magnets! In very high-end motors, it's becoming more common to use "funnels" of electrical steel to concentrate the power of magnets even farther. Pairs of magnets are tilted to form a triangle with the surface of the rotor- the flux is forced down into a smaller area, making it even stronger! That gives motors more torque for their size.

The case you've chosen looks to be designed with home theatre PC usage in mind so it's not ideal for high powered components like the ones you're chosing. There are still a lot of small form factor cases designed with higher end components in mind, that have more room for more fans and better airflow overall. Such as this case: https://www.amazon.co.uk/Thermaltake-Core-Snow-Mini-ITX-Window/dp/B00MJSV9Y2/ref=sr_1_26?keywords=mitx%2Bcase&qid=1565809430&s=gateway&sr=8-26&th=1

Which has much better airflow, as the top and sides have large meshes with plenty of fan mounting locations and a large included fan. It's a bit of a different design of case to the one you've currently picked however it should be a much better fit for the components you've picked while still being easily portable.

Whatever case you do end up picking though make sure it has enough expansion slots to fit your GPU and enough physical space to fit your GPU as well, and also make sure it has room for any other expansion cards you may wish to have such as a WiFi card.

If you want to learn the math/theory behind it, I suggest this book
It's actually one of the easier technical textbooks I've read in the sense that things are explained clearly and intuitively. But if you're looking to learn how to perform the simulations, then like others mentioned, using the software whether it's through tutorials or projects would be best.

Oh. Well... since I like you here's some stuff that will turn your bath into slime. Have fun.

If you're not already referencing John Keegan's A History of Warfare you would find it interesting.
