Yeah I would just permanently keep your tower on a desk or just move it up when its raining.
If you must be on a platform I would look into solid top pallets and maybe do two wide and maybe double high. I wouldnt be able to relax knowing my chair wheel might clip off the edge though so thats up to you
Googling solid top pallet will show you plastic options too which would be waterproof but will start to bend in the middle parts between where the legs touch the ground.
