Yeah, I tell my friends to use pcpp for drafting builds, although the component list is not great for older stuff, or for server gear (I just rebuilt a server, and while they claim to list Supermicro boards, mine and variants didn’t show up, while it is a standard micro atx). So trying to research what to build around, say a mobo and cpu that you grabbed from a thrift shop, can be hard if you don’t know what specs and compatability to look for. For new typical builds though, it takes a lot of the confusion and worry out of it for new builders.
A few years ago now, I used pcpp to draft a friend’s first pc, get funding for the project, and then helped the friend + father from box to boot (and way beyond, but) over a video call, and the most either had done before was replace a gpu. Booted first try, too.
Legos! :D
A moment of silence for the fallen 😔
