Already got a microATX rig so just need to replace the case. I mean optical drive slots.
I use 1 for bluray player/burner
1 for dvd/cd burner
1 for card reader interface with usb 3 ports etc
Ive currently got a CoolerMaster Elite 341 which is 40cm deep by 35cm high by 18cm wide but the main issue is that there just isnt enough height and width to it to allow for good airflow
Ideal size would be 20cm wide, 36-38cm deep & 40cm high
