Recently got a new case(Antec 900) and transferred everything into it from my old compaq case.
Here it is




Case has got two 120mm fans at the front with cool blue leds(see the pic), one 120mm fan at the back(exhaust)also with blue leds and one 200mm fan at the top which is absolutely huge and throws all the warm air out there, to give you some idea of how powerful it is you can make a £20 note float above it!
