Can the Hyper 212 Evo fit in my case?
I have an Ultra Defender ii ATX Mid-Tower case, and I want to know if the Hyper 212 Evo will fit in my case before purchasing it. If not, are there any other cooling fans that may fit that are around the same price and work just as well?
Yes, but with modifications (No, without modifications)
Alternatively, if you don't want to mod your case, depending on your CPU/MB's socket-type, you can get the better Cryorig H7 (only measures 145mm in height versus the 212 EVO's taller 159mm height), though it's $10 more expensive than the 212 EVO:

If you're not going to OC or you have a low-TDP CPU, you can also get the more affordable Cryorig M9 (model depends if you are using Intel or AMD), which costs only $20 (slightly lower price than the 212 EVO).
