Ideal print parameters are as follows:

This model prints nicely at 300mn or finer.

Base: The only support you may want to add is in the port openings in the rear, however, at 200mn, I have found even that area to be self supporting.
Top: You may add support under the front lip, however, I have successfully printed the top with no support material at all.
Face: This model should be printed face up, and support material needs to be added for the inside and perimeter.  I don't recommend printing this model face down, as the finish would be in my view unacceptable.
Internal Drive Support: No support is needed at all for this model, and it supports virtually all PC drives.

This case is design to use M2 heatsets with M2 screws (all screws 0.40mm Thread Size). 
Lid Screws: M2/12mm
Board to base screws: M2/4mm or 6mm
Internal mount to base screws: M2/10mm or 12mm
LED display board screw: M2/6mm
Heatsets: Tapered Heat-Set Inserts for Plastic, Brass, M2 x 0.40 mm Thread Size, 2.900 mm Installed Length
Hex key utilized for M2 screws is a 1.5mm hex pattern.
