outdoor pc box

i have a big outdoor plastic closet with shelfs in my garden. i want to place a pc with crt screen inside heating the space in which the pc and screen are to be located is 1/4 m3 (1 m wide x 1/2 m deep x 1/2 m height between the shelfs) or 1/2 m3 (1 m height) but with other objects sharing the space the computer is a pentium 1 (~40 W power). it is intended to be on for long periods with the door closed. the closet stands in a shaded place but air temperature outside can get to 35 C + sometimes. i dont want to cut vent holes in the closet the monitor (15 crt) is off when the door is closed. though i may switch it off and close the door while it is still hot how to prevent overheating ? is a water tank thermostat set to 45 C in the air near the pc (with the 240 V to the pc going thru it) good enough thermal protection ? insects we have lots of ants. how to protect the pc from them ? will the hot air in the closet be enough to distract them ?

place the PC outside, and put some sort of mesh to keep the bugs out
