Will this fit this

[SiKo]

I am currently going to purchase a, Shuttle 20th Anniversary Special Edition. I was curious will a, GAINWARD nVIDIA GeForce FX5900XT Video Card fit in the SHUTTLE. The heatsink on the GAINWARD card looks huge and I dont want to order this card if it wont fit inside the SHUTTLE. I have never built/used a SHUTTLE so any input will help. --Thanks
