Is horizontal pc alright?

Currently using gtx 4070ti notice and just noticed in but 2 weeks some sagging beginning to occur. I'm too much of a lazy piece of shit to get a frame to hold it in place, so wondering if it's okay to leave my pc horizontally like so? - has a glass cover as seen in photo.
