Case/component compatibility

[charmed]

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.

The components will all fit.
Thermaltake doew not currently show a 470w psu on their website, so to know whether its cables will be long enough will require a model# and a search for reviews that might be telling.
