A 8800gts should be fine without modding the case..sorry to hijack your thread, can you fit a 8800GTS into the fusion without modding it ?
Cheers...........I forgot about the power connectors going into the top of the 8800gtxi have this case, and tbh, you may have a great deal of difficulty getting the PSU mobo connector to reach as the grfx card comes nearly flush with the top of the case, all depends where the socket on the mobo is located, if the pics are yours then you will be fine
