That should be fun build! Thermals might be the biggest challenge, so you will have to play around with it. I am not familiar with that exact case, so can't offer any input there.
If you want to make the ps/2 ports internal, it's probably best if you are willing to do some hacking. You could take the external USB adapter and cut the ends off and solder to the connections on the bracket you linked. You would need another adapter to make the USB port and internal connection, like this: StarTech.com 2 Port USB Motherboard Header Adapter - USB adapter - USB (F) to 10 pin USB header (F) - USBMBADAPT2 https://www.amazon.com/dp/B002GNU2V6/ref=cm_sw_r_apan_i_B3SDXD02PRBB36RMH0K4
Good luck!
Honestly I don’t think you’ll have to do that. Once you have a working USB the disks should be recognized and you can set it as a “new setup”. I’m NOT an expert at this somyoull want better guidance than I can give for specific steps, the Limetech forums might be best, but I believe you’ll be fine once you’ve got a licensed working key. You are absolutely NOT the first to do this, I did have a backup though.
A suggestion, buy one of the little USB adapters that plug directly onto the motherboard header and move the USB stick inside of your system. I did that after trashing my first USB �� https://www.amazon.com/StarTech-com-Port-Motherboard-Header-Adapter/dp/B002GNU2V6
I agree with you that would be pretty sweet. But you can achieve something pretty similar with a USB header to USB female adapter and putting the unifying receiver inside your case.
I have one of these, one port has my unifying receiver, the other has an Xbox controller dongle. Works great.
If you've got USB headers open, I recommend one of these so that you don't have to run a usb cable outside the case.
Of course, they come in various sizes, numbers of ports, cable lengths, and USB versions. And they're pretty cheap!
If you have an open USB header on your motherboard, you can plug in a direct connect USB adapter there. Then, plug in your wireless USB adapter for your keyboard of choice. Problem solved!
Hyper-V can and does run happily from a USB thumb drive. Also, saves you a SATA port.
Once it's booted it has next to zero access of the boot drive, whichever media it is.

A much better "how-to" oriented guide: http://www.altaro.com/hyper-v/installing-and-running-hyper-v-from-a-usb-stick/
I did it myself just because I wanted to figure out how to do it. Turns out MS put some pretty heavy restrictions on the type of thumb drives that can be used, they have to report themselves as non-removable. The TechNet article references those models, and they aren't cheap.
I found a way around that, I used a micro-sd card to USB converter, cheap from amazon. It's physical format looks just like a thumb drive after the card is inserted. It was a while ago, and I don't have my notes handy, but some googling should show you how to flip some bits on the micro-sd card so that it reports itself as non-removable. Then just follow that how-to guide and it just works.
Further complication on my end, my TS140s don't have an internal USB A female port. But they do have an extra motherboard header for additional ports. I purchased one of these: http://www.amazon.com/gp/product/B002GNU2V6?psc=1&redirect=true&ref_=oh_aui_search_detailpage It plugs right into the MB header and then presents two USB A females ports.
It all ended up being quite tidy.

Those exist, too. You’re probably searching with the wrong words. Type in USB header adapter on Newegg or Amazon, not hub. Hub has a different meaning.

Not sure if this is the exact one, but same layout.
Plugs into the motherboard internal USB header (so you can't have external case USB if you only have one onboard header), then you plug the thumb drive right into one of the ports.
A quick google found this header-based adapter:

This card has a variety of different options available, ranging from internal headers to external ports:
