Placing a tower case with PS at the bottom on carpet?

I'm running in to an interesting issue, which I could use some feedback on. It's been several years since I've built a desktop PC, as I've pretty much moved to laptops.

I'm helping someone build a gaming PC and am finding that pretty much all mid tower cases now have the power supply at the bottom, with the fan facing down. While I understand why manufacturers have moved to this design, it causes a challenge for the type of surface the system is placed on.

In my friend's situation, the system would be placed on the floor which is carpeted. Is there anything I can do in this situation, like install the PS upside-down so the fan is facing up rather than down? This system will likely be running a GTX 780, so I want to be careful with airflow. "Buy a table" isn't a valid response here. If I can't do anything reliable with these new cases, he'll likely just try to buy an older case with the PS on top.

Is that all? Do I need to reverse the fan in the PSU to change the direction of airflow?

yes just flip the PSU so it gets air from inside the case, instead of the floor if the mounting holes support it.
Do not open the PSU and flip the fan, that's not a good idea.

otherwise, u could go out to a hardware store, buy a piece of wood, have them cut it to length, and then put the PC on top.

The PS we're looking at is the Corsair CS750M. It looked as if it would be fairly simple to flip the fan, but I'll make sure before it's purchased.

Thanks for the incredibly quick responses!

the mounting holes is on the case.

if the case doesnt support a PSU flip, u wont be able to mount it securely.

it has nothing to do with the PSU in your situation.

Ahhhh ... I thought you were replying to my question about flipping the fan. I'll definitely check the mounting on the case. It'll likely be the CM HAF 912.

Flip PSU or do above. Just need to get it off the carpet a few inches.

Personally, I would do both.... flip the PSU and get that thing up off the floor. I would also find some way to filter the intake fan(s.)

Home Depot (or your local equivalent) has fairly cheap ceramic tiles also. Buy a long, rectangular tile, put that on the carpet, put the tower on top of that. Works comparably to a piece of wood.

If you don't have a PSU intake filter, I'd concur with everyone else who's suggesting that you invert the PSU as well.

Edit: Also, there are still some relatively decent cases with top mounted PSUs if you'd rather go that route. The Rosewill Line-M is a decent budget mATX case that can frequently be found for less than 50 USD, and has a top mounted PSU.

Another is the Fractal Core 1000.... but you are limited to 2 HDDs.
