I agree with Bentheball1. The items you linked to on eBay are a complete system of fans with lighting effects. They do not "fit into" any of the currently common systems, so they are "non-standard", if you will, and cannot be mixed with anything else. I see two major issues here. The first is that the MOST important aspect of this is the fans - how much air flow they generate, how much noise that makes, and especially how long the fans will last before the bearings wear out. As a general "rule", cheap fans don't last long. The second is that control BOTH of the lighting effects AND of the fan speed is entirely manual. That is, YOU are responsible for using the remote control device for setting the fan speeds to ensure proper cooling at all times as your workload changes. How do you decide what speed, and how much time do you want to spend changing speeds?
That system would cost you $36 for six fans, each capable of 33 CFM. If you arrange them as three fans each for intake and exhaust, the combined air flow would be about 33 x 3 or about 100 CFM. As an alternative, consider this example.

Four of these would cost you $54. Their individual air flow is 59 CFM, so two each as intake and exhaust could deliver close to 120 CFM, more than the set of six you proposed. These are from a well-recognized maker and use common standard connections and control methods. For each fan, there is a fan motor control cable that connects to a mobo SYS_FAN header and uses the new PWM Mode of control. Then there is an RGB lighting control cable that plugs into a mobo plain RGB header. But to add FOUR of these, you would also need an RGB Splitter cable to connect them all to the single mobo RGB header. Then you use the software utility that comes with your mobo to control the RGB displays, and the automatic fan speed control ability of the mobo fan header to do all the fan speed control (and hence cooling adjustments) automatically for you. There are certainly other makers of such fans, too.
Following Bentheball1's suggestion, another option would be to add the Phanteks RGB halos and an adapter cable to your existing fans without actually adding more fans. This involves removing those fans and re-installing them with the halos in place, then connecting the halos to some RGB
Now, that system would require that your mobo already contain certain features. You would need some fan headers (SYS_FAN or CHA_FAN) and maybe some adapters to connect several fans to them. You also would need the correct type of RGB header on your mobo, and there are two types that are incompatible, so they have to be matched properly. Moreover, since you already have a working computer in a case with some fans included, all of that hardware needs to be taken into account. That includes details like how may fans of what type do you have already, what spaces for fans does the case offer and where are they, what features your mobo has for controlling fans and lighting accessories. etc. So if you want more specific advice, post back with some info we need:
- Maker and model number of your computer system, if it was a complete finished system and not one you built.
- Look at labels on your existing fans. Can you find makers and model numbers, and how many of each type?
- Look at your mobo, and tell us its maker and model number.
- Where do you need lighting effects displayed in the case? For example, if the rear exhaust afns are never seen, you don't need RGB lighting effects in them.
With that we can see exactly what additional components might work for you. To start I would assume that you want to continue to use your existing fans and just add new ones, and keep costs down.
