I am not the tceh person but 4 hours work on it with cousin and at the end decided to collect new pc!!!
You gotta learn at least the basics. Otherwise how are you going to build a new pc and mine with it? Building a system is a lot easier than successfully mining with it, you'll have to learn so many things that you might as well start from basics anyway.
But still if you decided to build a new PC, and all you have is just one card, then pretty much anything will work. Any motherboard with pci-e x16 slot, any case that your card would fit in (matx tower or larger) and a PSU that has at least 400W of power on the 12V rail (any decent 500+ W ATX PSU will work). Pretty much 99.9% of typical PC hardware will work for you. People come here to select motherboards that allow to run 6 graphics cards or more.. that does pose some challenges, but for just one card you can use almost anything. Your fujitsu could probably work as well, provided it's a standard factor PC and not some thin client or something.
