So I will complete the Dreamcast build, because I want it done even if at the same time I don’t want to spend money 
Will surely run Windows 11 preview on it and maybe use it as a media center.
Went for a cheap 3200g from ebay and have a deskmini x300 on rebate from newegg coming my way. Will buy also the ram tonight, but waiting a little more maybe I have an answer from a guy on kijiji with a set of ram at a really good price.
I have still the nvme ssd and noctua cooler from my previous build.
