Welcome to the Forums!
I looked into it and it can be installed to face the rear of the case. I think the biggest issue will be if your ram slots are far enough away from the cooler to install the ram. Otherwise you will have to remove a fan.
In terms of A70 vs Hyper 212+, I'd say the A70 is probably slightly better. You do get an extra fan, which is a bonus. However, the big deal behind the Hyper 212+ is it regularly goes on sale from $10-$20 AR and with the performance being pretty good, it is hard to beat at that price. With the current prices of $35 and $27 it is a toss up.
