[SOLVED] Need help with PC airflow and CPU cooling

Hello
I have just bought a prebuilt PC, but quickly sumbled upon a problem. The airflow in the case is horrible.
To combat this I've decided that I should replace my CPU cooler, add two extra fans on the bottom and another one on top. But I'm a bit concerned that it won't work, so I would like to consult some experienced PC-builders.
Here is a picture of it, where I've crudely drawn my ideas and the existing fans on:

The red outlines are the fans I would like to add. The blue are the already installed fans.
Does this help the airflow or am I completely off?
The 92 mm fan does not have a hole at the moment, but I plan on cutting holes where the white tape is (there is also some space between the front panel and the metal chassis). Is this a big enough hole?

I would also like to know if an AIO would be better than a low profile air cooler? Since I don't have a lot of space (only about 120 mm of height), my options are quite limited: it's either a low profile air cooler, or an 120 mm AIO. From what I've read, the air cooling is the best in general, but is an AIO better that the smaller air coolers? (This is a bit of a stretch, but can you buy the liquid cooling, from the Omen Obelisk that featured said cooler?)
Secondly I would like to know if the power supply is going to cause some issues. It only has 500 watt, and I don't know how much of it is in use, so I don't know if there is enough.
Another power based question is if I use two PWM splitters will the fans RPM or wattage decrease?
Thanks in advance!

It is.

What prebuilt is that?

Honestly, rather than acquiring new fans, cutting holes and replacing the cooler - you might be better off transplanting to a cheap case with better airflow (and a couple of included fans).

Its the Omen Obelisk
I'm not so keen on replacing the case, since I love the apperance of it, but I'll think about it.
I also think it might be fun installing fans, cutting holes and all that :)
