Thanks for all the comments. I forgot how much fun building a PC can be if you are willing to take a gamble and troubleshoot where needed. PCs are now so powerful and the back catalogue of PC games so vast, that even with a modest build you can open up a huge library of games with used parts.
Great build and blend of parts for the money. Really like the orange case. Just building my first PC after 15 years so great to read your article. Good to see that you've included the Windows licence as it's often excluded.
Great to see older parts being recycled and not sitting in landfill, well done.
