Thanks m8. Actually had some progress this weekend. Got two spanking new
computers and I have been working on getting them up to speed the way I
like it. Primary computer is pretty much done. Secondary computer is 80%
of what it's replacing and 0% of the additions I'll be adding on.

I cleared out all the old computers, cabling of all types, and freed up
an immense amount of space on my rack. This is where my solder station
will be stored and various projects.

So when I get started back up, they will be in my face. Major project in
scope right now taking focus from this hobby.
