Hello, I'm terrified I've made a big mistake by buying an Inspiron 530s, that's the slim case version of the 530. I hadn't seen a photo and stupidly didn't think through how it being 'slim' would effect the compatability. My wireless card doesn't fit because it's too wide!! Oh god. So I've tried to see if I can find some advice online about which one to buy but I can't. Could anyone please advise? I'm also looking for a graphics card for the same purpose but I'll post it in the appropriate forum. Thanks.
