They aren't equal in terms of performance even they (Intel vs AMD) have same speed/core.

FX (Bulldozer) series CPU is using modules with 2 integer cores in each modules as "core", it is excel in those software/games which make use of it, but a dual core i3 can beat the highest end of FX series CPU in game if the game is operating in single threaded way.

Your CPU is ok for modern gaming, just upgrade the GPU and PSU for the time being.

AMD R9 390 and a decent 600W PSU will cost you around 2k+/-.

Front and bottom as intake while rear and top as exhaust.

RM 800 can get high end AIO water cooler already, if you are going for air cooler, no need RM 800.

i5 6600 is a locked CPU (or did you use the Skylake non-K exploit to oc it?), any sub-RM 200+/- air cooler will do the cooling job just fine like CM Hyper 212X or Cryorig H7 or H5 Ultimate.

Difference is quite significant, I tested i5 4460 few months ago with Corsair Hydro H100i and CM Hyper 212X.

H100i is able to keep the CPU < 40°C all the time when during max load compared to 212X's ~55°C, 55°C is still a very good reading though considering the weather in Malaysia is so hot.

If you are willing to spend so much just to get the extra ~15°C, then go for H100i V2 for 240L, H115/NZXT Kraken X61 for 280L, the rig looks nicer too with AIO liquid cooler

It depends on what is your priority.

If you install at front, the fans on the radiator will take fresh air into the radiator, CPU will be cooler while the rest of the components will suffer due to the increased heat dissipated from the cooler.

If you install on top, the radiator will suck hot air out of the case, CPU will get those warm air while the rest of the components will be cooler.

This might create strange/negative airflow

BTW Kraken X61 is 2 x 140mm.

Actually you don't have to worry so much on this, the difference in delta temperature is just few °C for intake/exhaust radiator setup.

You can go for push and pull setup on radiator too, just like what we can do with air cooler now.

Just get 2 more 140mm casing fans and install on the other side of the radiator which doesn't have fans installed by default.

Yup, total 4 x 140mm fans.

If install on top then most likely not enough clearance, front still possible.

Intel Core i5 6400 - RM 782
Gigabyte H110M-DS2 (D4) - RM 289
Corsair 8GB DDR4 2133MHz Value RAM - RM 162

WD Blue 1TB HDD - RM 215
FSP Hexa+ 550W - RM 188
Tecware Alpha Black - RM 219

Total: RM 2554 (ETech price inclusive of GST)

The case comes with 2 front intake fans and 1 rear exhaust fan, so I don't think you need to buy extra casing fan anymore, unless you want to add another 2 more exhaust fans on top.

You can downgrade to i3 6100 (RM 487) to save money if your usage is light/moderate, i3 is more than enough to handle Dota 2, I included i5 in the list mainly because I am not sure how's your daily usage pattern since you didn't mention them in your post.

SSD is not included.

Can downgrade, i3 is sufficient for your usage.

Normally the mobo will reduce the speed of the fan when temperature is low, PWM fan can also be controlled using 3rd party software like Corsair Link (require Corsair Commandar Hub or selected Corsair AIO Liquid Cooler) and SpeedFan.

If this is not useful for you then non-PWM 3-pin casing fan is enough, it is cheaper as well.

If you plan to get a fan controller in the future, then you don't have to get PWM fan since the controller can control the speed of non-PWM fan by adjusting the voltage supplied to it.

New Intel Skylake (6th gen) CPU supports DDR4 RAM module.

About your testing, what kind of test you would like to carry out? Overclocking it?

If it is solely for real life daily task (browsing, basic workload etc.) then it is very hard to notice the difference between DDR4 and DDR3.

I see, I have no idea on disassembling the RAM module, but will recommend a rig based on DDR4 and your requirements.

Since you only stated 24/7 daily usage and no gaming mentioned so basic i3 should be able to meet your requirement.

SSD will not improve frame rate, only loading speed.

Sapphire R9 390 8GB GDDR5 Nitro - RM 1549
Corsair Force LE 240GB SSD - RM 369

Monitor choice:
1. AOC G2778VQ FreeSync - RM 989 (FreeSync monitor, but it is 60Hz & TN)
2. Acer XB240H 144Hz - RM 1169 (High frequency, but usually you won't be able to achieve 144Hz on those games listed, very good for games like CS:GO and racing games, but it is using TN panel)
3. Dell U2417H InfinityEdge - RM 1139 (The famous Dell UltraSharp InfinityEdge monitor, successor to U2414H, one of the best 1080p IPS monitors in the market with thin bezel)

It is pure dual core (G4400) vs dual core with extra virtual core/thread (i3).

For Dota 2 and light browsing, difference is quite small, if you are planning to upgrade to i5 later then I suggest you to pick G4400 first.

DDR4 base clock is 2133MHz.

1333MHz is most likely a DDR3 RAM, which is the base clock for DDR3 RAM during Sandy Bridge (2nd gen) era.

DDR3 RAM will work on Skylake system but you need to get a DDR3 based Skylake mobo for it.

Add another 4GB of RAM.

If you aren't satisfied with gaming performance, I suggest you to wait for next gen GPU before you upgrade it, 7870 isn't that bad after all, should serve you well in the next couple of months till new card arrives in Malaysia.

Since you didn't mention budget, I will go with CM Hyper 212X or Cryorig H7, both priced around RM 150+/-.

Actually stock cooler will do that cooling job just fine since you are using a locked i5 (non overclockable), but stock cooler is noisy and less efficient than aftermarket cooler, the weather in Malaysia is very hot too.

There are 2 major types of CPU cooler, air cooler and liquid cooler. Air cooler is sufficient for locked CPU, the 2 coolers I listed just now are air cooler with better cooling efficiency and lesser noise.
