Problems include:  
1.  EMF generation, EMI suseptibility
    (especially if you put an AC-powered fan next to the system)
2.  Poor airflow over key components (you need airflow!)
3.  Dust

I've been using systems with 92-120mm intake-outtake fans for some time
and they keep the components cool.

My favorite designs include:  
- MicroATX Cube (120mm outtake fan over CPU, PS outtake fan over slots)
- Flipped ATX Design (dual-120mm intake-outtake for CPUs)
