# Homemade Computer Project To Be Named Later
# Model-A Homemade Computer Project
Here are the files used to build the case for my homemade
computer. You can see a lot about it in [this article](http://ralsina.me/weblog/posts/so-i-built-a-laptop.html) (or at least about it as it was in early march 2023)

* The component library is very limited (just the things I am using in my build)
None of those things is an insurmountable problem, and I am working on them,
and I have plans to fix it all. Eventually. Some day.
and I have plans to fix it all. Eventually. Some day. I only do this on
lunch breaks and weekends folks.
