Is it better to have a PC tower on the table or floor?

Hello there, I'm curious about something regarding PC towers. Specifically, I'm wondering if it's better to have a PC tower on the table or on the floor? There are pros and cons to both options, of course, but I'm trying to weigh them all out. On one hand, having the tower on the table might make it easier to access for upgrades or repairs, but it also takes up more desk space. On the other hand, placing it on the floor frees up that desk space but might make it harder to reach in case of maintenance. What's your take on this? Do you have any experience with either option that you can share? Thanks in advance for your insights!
