so my thermaltake armor full tower case and corsair 620 HX PSU are coming tomorrow...still don't have a mobo, processor, or any of the DVD drives or hard drives so I can't build it together. Problem is the 25 dollar and 20 dollar mail in rebates are due 20 days after purchase ( meaning when I ordered not when I recieved I'm guessing ), so I doubt I can get my other stuff in time to put them together and test the system. Should I just risk sending the mail in rebates? ( for those of you who don't know, when you send in the mail in rebate it requires the original UPC code on the box meaning if the item is DOA or defective you can no longer return it after sending in the rebate ) What are the chances I will get a defective PSU and Case?
