You missed to say what games and how many bots on those games you plan to use, because 3x WoW bots = 1x Diablo bot (or something like that), so it's still very dependant. About the Intels, like I said, they are BETTER or at least on the SAME level of the FX-8150/8350 when it comes to GAMING (A SINGLE INSTANCE OF THE GAME AT MAXIMUM SETTINGS), when it comes to multithreading, the FX wins over the other 2 Intels. FX-8150 can be clocked at 4200 MHz "right out of the box", and YES stock coolers ARE NOISY, you just can't say that a stock cooler (80mm fan at 5k+ RPM, it will run at 2-3k RPM while in IDLE, not while it's under 80%+ load and the CPU is burning, then it will start spinning as much as it can, high CPU usage on big CPUs, require a good cooler, no matter what you say here I just won't agree on anything else) will be silent, that's just impossible, as for the cooling, there are a lot of cheap and good coolers that will do the job. Temperatures? I think you miss the point here, Intels are WAY WAY WAY more hotter than an AMD, my FX is running at 43-46C under 80-90% load with a medium cooler, do I need to say more? While an Intel, will be at least 15C hotter...
About the PSU, you miss a looooot of things about it, any system, above 350E would require at least 400W, like I said use Power Consumption Calculators, you will see for yourself.. If you're using a mechanical hard drive, the initial spin requires a lot of power.. as for the MB, don't go for sabertooths or crosshairs or whatever, that's gaming and high end overclocking stuff, unless you aim for that, you don't need it, you don't need to overclock at 6GHz (I guess?) but still a motherboard that costs 40-50E, I wouldn't go there ... at least for now

I can't give any real statement here, but I just won't trust such expensive system on a cheap mobo/psu. Overclocking can and will increase the number of bots that you can run, and yes it is true that it reduces the lifetime of the CPU (It won't run for 8 years, it will run for 5 years, do you care? I don't, you'll make the CPU money like 50 times by then)
For the CPU, I'm sticking to 8150/8350 if we are in this price range, if we go higher then my hands are for them Intels, but for now I'll hold on to the AMDs, it's just better for multithreading, I am saying this for 5th time now, Gaming, one game, single instance of a game def Intel... Multithreading, botting, if we stick to this price range (~200 eu) then I'm all for the AMD.
P.S.
Cooler Master Hyper 212 EVO CPU Cooler Review - X-bit labs a very good and cheap cooler, all you need is just one extra fan to do push-pull.
Edit: at the time of writing this post I didn't realize that there was a 4th page here, so let me finish....
First, how do you exactly think that you are going to use the HDD from your Laptop on a Desktop PC? They are WAY different. Laptop HDDs are SLOW, it won't help you. For HDD like I said few posts ago, go for WD Black Caviar, they are very good and not expensive.
If you want to run a lot of bots, go for 32GB RAM, no question about that.
20 WoW Bots are less than 20GB RAM, 1 WoW bot is around 700-800MB (including HB)
Corsair H100 is not needed, unless you want extreme overclocking, check the cooler that I posted above, however if you want a really good cooler, check Noctua NH-D14, cheaper than the H100 and almost as good, water coolers, too much trouble.
