I've been doing something similar for awhile. Using my old laptop (damaged keyboard just like OP). Set 'lid close' to "do nothing" (it runs 24/7 with the lid always closed). Connected to TV via HDMI.

Only app is browser. Shortcuts for streaming and movie/tv reviews etc. Use the TV regular remote for volume and on/off. Use remote mouse 90+ percent of the time. Keyboard only when my preset links are insufficient and I need to type.

Have the same setup in the BR (running on a used mini-Optiplex I bought for $135). Works great.
