Knightly/Monastic Chapters that AREN'T Dark Angel's or Black Templars?

So todat I came into possession of the Black Templars army box someone was selling off and the whole 'knightly' aesthetic has never appealed to me, so as far as SM goes I've always been turned off by the design and gravitated more towards Space Wolves and Salamanders successors visually.

I like these models, but I truly, and purely do NOT want to do them as Black Templars or Dark Angels, so does anyone know some chapters that have the same Monastic and robe-happy visual flair? Appreciate it! ^-^
