I'm using ml07b for 3years already. No prob so far. Like the slim look.

However these are the pros and cons that i can think of

Pros:
Slim and small foorprint
Can fit regular sized graphic card but got length limit
No overheating issue. The case has great cooling. I use noctua fans and scythe cpu heatsinks.
Can fit laptop cd rom, 3ssd, 1 hdd.

Cons:
Expensive for a bare case - no psu, fans, dust filter bundled.
Uses sfx psu, limited choices
Stiff power button, reset button. Hard to press.
Plastic build
My gpu runs hotter when lying horizontally. Gpu will face down and cause insufficient airflow. I keep it vertical at all times for now.
Cpu heatsink need to check for height clearance as it may not fit the slim case.
