Go to Home Depot or Lowe’s and buy a 12x24 tile sample for like 3 dollars and put the PC on that.  That’s what I do, works great and provides more stability for the tower.

Every shattered tempered glass side panel is sitting on tile/stone. I cut an old wood shelf that looks nice and does the same thing.
