and to be honest there not going to know which cooler has been used!
Well, "
to be honest" is an ironic choice of words, no? If that 3rd party cooler dies and something happens to the CPU, "
to be honest" will also require you to tell AMD exactly which cooler was used, in which case, they don't have to honor the warranty. Please understand that neither AMD nor Intel want to be replacing CPUs because the supplied fan failed during the CPU's 3-year warranty period. For this reason, the supplied stock fans are
excellent coolers and do an excellent job of removing heat from the CPU, where it is then the case's job to extract that heat from the case. Note the Zalman is only warrantied for 12 months.
Oh, and also note that the warranties for both AMD and Intel require these CPUs be used with specified voltages. That means damage from overclocking is not covered either. And of course, no motherboard maker will cover damage from overclocking, even though they may provide (and highly market) overclocking utilities with the board. 3rd party cooler makers won't cover damage to the CPU or the motherboard from excessive heat either. Not sure if overclocking is something you are planning, but I think it is important to understand the monetary risks.
Also note that fancy lights (like that on the Zalman and your selected case fans) do nothing for performance, consume some power, generate some heat, and do nothing for performance (worth repeating). That case does not have side windows so it seems to me where there is a budget involved, the money would be better spent elsewhere. IMO, a case should sit discreetly and quietly off to the side and not draw attention to itself - after all, it is what's happening on the monitor(s) that's important. That said, I think you are wise to include a second fan presumably for the front of the case, but understand it is the case's responsibility (with the fans) to create the necessary front-to-back flow through the case. Therefore, when you buy case fans, the important criteria for their selection (besides size) is CFM, then dBa (noise level). Looks are not a performance criteria. Fan noise is the result of fan blade design and the quality of the bearings. Generally precision ball-bearing or fluid-based bearing are the best. Based on the price and lack of important description details of the fans you selected, I would be worried those fans use cheap sleeve bearings, are noisy, and don't move a lot of air, or do so sounding like a jet engine. A good case fan will state the bearing type, CFM and noise levels so you can compare.
If you must go wireless then Wireless-N (802.11n) is the way to go. While 11n is much better than previous protocols at interoperability, I am still seeing where mixing brands between the WAP (wireless access device - often integrated into wireless routers) and the computer's adapter results in connectivity issues, so if possible, I recommend using the same brand as your WAP. If not available. I still prefer adapters with external antennas. That adapter you have selected resides entirely inside your case, which is basically a metal box. So the antenna is set in a fixed orientation inside a metal box too. As an air traffic control radio technician for 20+ years, putting an antenna inside a metal box (typically down close to the floor) just does not make sense to me if you are looking for range and quality (thus fastest) performance.
I might suggest a different card. Note this
Cisco has two external antennas that you can change orientation for best performance. There are other adapters that have removable antennas that allow you to position them higher up, and away from nearby electronics and rat's nests of wires.
Finally, if you need to buy power splitters from day 1, it seems to me you need to select a different PSU. I like Antecs but if that one does not meet your needs, get one that does. I also like Corsairs and have recently used several Mushkin supplies which are so quiet, if not for the little power light, I would not know they are running.
