Claim:
A computer enclosure comprising: a bottom casing; a top casing detachably connected to said bottom casing and defining an opening; and an engaging device comprising: an upper unit attached below said opening, said upper unit comprising a bracket, and a first lever pivotably mounted to said bracket, said first lever having a first end extending through said opening in a first position and a second end; and a lower unit attached to said bottom casing, said lower unit comprising a first driving portion and a second driving portion; wherein when said first lever is located in the first position and is rotated downwardly to a second position, said second end drives against said first driving portion of said lower unit to cause said upper unit to be moved in a first direction, thereby attaching said top casing to said bottom casing, and wherein said first lever is generally fully received in said bracket when said first lever is located in said second positions; wherein when said first lever is rotated upwardly away from the second position to the first position, said second end drives against said second driving portion of said lower unit to cause said upper unit to be moved in a second direction that is opposite to the first direction, thereby detaching said top casing from said bottom casing; wherein said engaging device further comprises a second lever pivotably mounted to said bracket; wherein said second lever comprises a pressing portion, and a catch formed at a front of said pressing portion, and said first end of said first lever comprises a step for engaging with said pressing portion.
