Well, my expectations are not to blow up the computer XD
I was expecting to spend around 40€, but could rise it to 80€ if the difference is worth it. RGB would be neat, but not obligatory. The motherboard, the ram and four 140mm coolers that the case has are RGB, so I'm served in that matter. In the case of sound, I pretty much use the pc all day, so I rather not have a plane rotor in my ear constantly.
I was curious about water cooling, but I've never used it before so I'm not sure. It can look really good or go really bad if I install it wrong and leaks.
