Hi all, Well it's that time of year again and i am once again buying parts for my husband’s computer! I want to buy my husband a new case for his computer (as his computer currently has problems with overheating). Hence, is the 'Antec 900 gaming case with 200mm top fan' compatible with his current components an ' ATI Radeon HD 3870 graphics card', an Asus P5GD1-VM motherboard and a 'Thermaltake 470w psu'? Hope someone can help! Thanks in advance.
