I want my report to look better

I have a daily report that I wrote and I really want to rewrite it, I would like it to be much neater looking, and I just want an overall better look to it. Of course I'm aware of the fabulous vCheck script, but for our environment, I want something with less information that people (besides techs) will look at, I also want to write it myself.

The main help I want is really just advice, I don't want actual code, because I want to write this all myself. I want to incorporate html directly into the email output, right now I'm using out-string when I send out the email and I want that to change. I know there is a -BodyAsHTML parameter when sending the email, so that will be good to bold and color sections of the email. I just need to use it correctly. I have all these ugly looking functions with code here, then text there, and I just know it looks bad underneath the hood. In email it was looking good, that is until I saw it within outlook 2010, in outook 2007 everything lines up, but in 2010, everthing is just off center, and that's one of the main reasons why I want to rewrite it, that and I want it done right this time.

I have omitted the private data from this post, but this is the script.

The actual email that goes out is at the bottom of this post, I just changed some of the numbers, because I'm overly paranoid.

Thanks for taking the time to look at this post, I know I have a lot on here.
