This came from a Vertical Wave server. How would this be classified as-is, and how about if I removed the yellow transformers? Thanks!

The amount of Cu transformers/coils on the board puts it in High per actually.

Remove the transformers and you have Low Tel for sure.

Another note to take, there's a lot of empty space. Keep that in mind when thinking of removing items for upgrade. Space makes a difference when there's no material to capitalize on and you're removing maybe the only thing it gave it weight/value/upgrade.
