That looks like an AIO, as everyone's said it's just a pass though not a capture so you could in theory use it as a monitor when the system stops being relevant. If you had a desktop proper you could toss in a pcie cap card to play off of. I'm running a Avermedia c027 which although is limited to 720p doesn't have any discernible input lag.

Literally lost track of the number of computers I've built in the last 4 years. Have never cared about ESD, but if you're worried touch a light switch and you're fine.

I can't speak for using disk2vhd for virtualizing anything other than windows, but it should be doable. It's kind of round about but at the bare minimum you should be able to image the hard drive using DD to an IMG file and use VirtualBox to convert resulting image to virtualbox's proprietary vdi. Some settings would probably have to be tweaked but it should be able to boot then you can delete what ever partitions you don't need, if your windows and linux are sitting on the same disk. And if you want to convert the virtual disk to something that works with something other than Oracal's software you can just attach a new virtual disk to the machine in the format you want and clone the os over to it, this has been the easiest way I've found to convert disk images there might be an easier method. With all of that said that would be if you wanted to convert your stuff to Vm and not keep around the install. After a quick google search though it would seem it's possible with oracles virtualbox to load up a OS on an attached drive via "Raw hard disk access". I can gander that it should be possible to load up the os existing on the same drive as long as you never try to boot into the Host os from the virtualization. So like if you're chainloading the windows loader via grub maybe increase the time threshold to do that, or just don't chainload the windows bootloader as you haven't needed to do that in years.
