Is there any way to install an 80mm case fan into a Fractal R4 case?

[Billspear]

I'm looking to buy a Fractal Design Define R4 and the specs list 120/140mm fans as being compatible. Does that mean that there are only holes drilled to install those two sizes? Sorry, I'm new to PC building. The case is here:

The fans I'm looking for are these:

If it's not possible, is it safe to drill holes in the case? I don't want to ruin it. Also, does anyone know of any fans that are similar to the one listed above? I love the neon green color. All other green fans that I come across are more of a forest-y green. Any help or suggestions are greatly appreciated!

You shouldn't have to drill holes in the case to mount them, You can buy cheap adapters for the case. Although why? A 80mm fan is quite small, meaning more noise and less efficiency.

If you want purple LED'S try these.

They're top end fans and do their job really well and are 120mm.

Although if you want green fan with purple leds it's going to be quite hard to find one as such, in that case it's not recommended but you can buy adapters.
