I just purchased the parts for my first homebuilt computer, and now I need to build it. When I was asking around on homebuilt, they said that cooling might be an issue since my graphics card vents into the case, and I'm using the stock 3770k cooler.
I can't accept that price for the D14 when it really isn't "that" much better than the 212. Especially when you can get a second fan on the 212 and creep even closer to the D14's performance and at $40 or so.. it's worth half the price.
I'm not absolutely sure, but I believe the 212 will fit in that case you had chosen and know it fits in the Thor v2 with probably two inches to spare.
Hope this helps. Looks like a nice build you have selected ptudia! It definitely will be a fun first build!
