Since most of the body surface is mesh, it quickly collects dust, which is not aesthetically pleasing and needs to be cleaned frequently. Some pros: 1) Very easy to assemble 2) There are rubber "plugs" for wires 3) Dimensions that are very convenient for me - wide enough, blowing goes in front, behind, below and above, and not on the sides (What is + if it stands under a table or in some special opening for a PC) 4) There are dust filters 5) Small for high-performance systems with multiple graphics cards, but there is enough space for everything for a home / work PC 5) there is a place for dropsy Different cons: 1) Poor sound insulation, as they sacrificed excellent ventilation for cooling.
