Dota 2 requires a better specs to max out the graphics settings at 1080p144.

CM Elite 130 should be the cheapest option (less than RM 200) for you but it might be a little bit too big for you to hand carry it.

Other small mITX casing is also available like FD Node 202/Silverstone Milo series but you will need to change your PSU to SFF PSU (sell off your RM650 and use the money to get a SFF PSU, price starts from RM 400+).

Well the cheapest GTX1070 costs nearly 1.8k already, so you left RM 200 for the rest of the items, I don't think it is possible to get all of them at once for now.

It depends on your usage, 6800K packs with lower core clock speed but with 2 extra physical cores compared to 6700K, for single core performance on stock speed, 6700K is faster due to higher core clock speed. If you use it for gaming only then 6700K is a better choice, save the hassle to overclock and fine tune the 6800K to match the speed of 6700K (5820K is obsoleted and I am going to skip it). What's your budget for the CPU cooler? If you are going to apply some mild overclocking then mid end air CPU cooler is enough (around RM 200), if you are going "all-in" mode then you can consider high end AIO liquid CPU cooler (RM 500+).

And for GPU, you will need to compare the full specs 6GB GTX1060 with GTX1070 8GB instead of the 3GB variant, performance difference is roughly 40% (GTX1070 leads).

1080p60? GTX1060 6GB
1080p144? GTX1070 8GB
1440p and above? GTX1070 8GB or GTX1080 8GB

Yes you can overclock the card to match the speed of other cards manually (hopefully you are not lazy to do the overclock ).

Alright if you plan to reuse your processor, you might need to look for used mITX LGA1155 mobo because new one is nowhere to be found now. A full CPU platform revamp with Skylake i5 + H110/B150 mITX + 8GB DDR4 RAM will cost nearly 1.5k.

Ultra or ultra high on 1080p with a max budget of 3k is quite ambitious, though it is still possible if the game is well optimized for mid end hardware.

Nope, 6GB is indeed a much better choice if you aren't being restricted by your budget, more and more triple A titles use more than 4GB VRAM now even on 1080p resolution only. And 3GB VRAM model is not running the full GP106 specs (only around 90% raw power of full specs GTX1060 6GB GP106-400).

Which aftermarket card is good? Hmm, if budget doesn't matter, then those high end models like Asus Strix, Gigabyte Xtreme Gaming, Zotac AMP Extreme (and much more) are pretty nice, but it could cost you extra few hundred in return for no performance improvement though (just few FPS ahead)

Yes possible, it can be either with locked i7 6700 or overclockable i7 6700K. Lowest end hexa core Broadwell-E is also possible.

Overclockable i7 6700K build is also possible with your budget. GPU/Casing/mobo/PSU model can be changed according to your own personal preferences

Not quite possible.

Intel Pentium G4400 - around RM 250
Cheapest H110 mITX mobo - around RM 280
Cheapest 4GB DDR4 RAM - around RM 140
Cheapest 1TB HDD - around RM 220
Cheapest compatible PSU - around RM 100
Cheapest mITX casing - around RM 150

Total cost might be over RM 1140.

Always refer back to the seller (that's why always pick a reputable seller just in case), most of the local distributors don't deal with end customers directly and they will ask you to RMA the item via the seller or retailers instead.

Legit, from DotaTech right? The CPU isn't the highest end (in fact it is the lowest end Skylake i5) and the other components are well within the total cost.

Gigabyte Windforce OC seems to be the most worth buying card for me in this comparison, I wouldn't be paying extra RM 100 just for the extra factory pre-overclocked speed which I can manually overclock myself and save me RM 100 for other parts, and the appearance between the Super Jetstream and Jetstream model looks almost identical to me (well I expect to get something different in terms of its external appearance when I pay more )

Any mITX chassis will do? Is there any special requirement like the size? Card height? HDD/SSD slot etc?

If you are looking for 1ms panel, then you can consider Dell SE2417HG (1080p TN). As for IPS then you got few options like Dell S2316H, ViewSonic VX2363MHL, Acer R221Q etc.

There are few possible builds with your budget, if I were you I will go for this.

Overclockable i7 6700K build is also possible, but you might need to lower down the specs of certain hardware (like SSD/PSU/casing etc.) to cater the cost needed for 6700K + Z170 mobo.

Yes it is very difficult to build from scratch with your available budget, both of the rigs above aren't worth to invest anymore now, some of them are very old already (like the Core 2 Duo, 10 years anniversary ) and you might face even more issues running the latest games (and upcoming one) with those specs, I recommend you to get a Skylake i3 build (without dedicated GPU) first and use the iGPU of the CPU (HD 530) to play games for the time being, add a dedicated GPU later when you have more funds, this is a more feasible solution to me.

Cannot comment too much without listing out the exact brand name and model because the price difference between all the models and brands is pretty large in Malaysia

If gaming only then you can save a bit more by getting the locked i7 6700 and normal H110/B150/H170 instead of i7 6700K + Z170 (expensive). And CPU cooler is missing in the build list, you need to buy one for the CPU to work because K series CPU doesn't come with stock cooler anymore starting from Skylake.

The better word for "mod" is "overclock", mod involves changing the appearance of the part which is not possible without voiding the warranty (or spoiling the item), FYI, overclocking doesn't bring a lot of performance improvement in gaming, it could be none at all if the game you play doesn't benefit from high speed CPU, spend the money in other parts (like getting a better GPU) is a much better choice.

Corsair VS and Silverstone Strider Essential are under same tier (tier 6) while FSP Hexa is under tier 7, they are super low end PSU and you can try to get the Corsair or Silverstone if you want a slightly higher rating PSU than the FSP (tier 6 vs tier 7).

And the SSD, yes you can change to SanDisk, the difference between SATA based SSD is not huge so you won't miss out a lot in terms of the I/O performance.

The price difference between 20" and 22" FHD monitor is very small (less than few bucks), 20" monitor usually comes with a very bad contrast ratio which you might find it difficult to adjust the contrast and brightness to your comfort zone when you are in a dark room. Nevertheless, here is an updated build, I have to downgrade the CPU, GPU and casing to fit everything in your new budget.

Yes you can, most likely can fit a GTX1060 3GB (6GB might still possible with some top up), I saw the games you listed in frequently played games list weren't that GPU intensive so I went ahead and included a SSD in the build list instead initially, it is completely fine to drop the SSD and opt for a better GPU in this case.

Look for Palit/Zotac branded GTX1060 for budget card.

6500's single core clock speed is higher than 6400 and 6402P by quite a large margin, apps which rely heavily on single core (or single threaded operation) will benefit from the higher clock speed of 6500, so in general, it will only affect the time needed to finish a render (slightly longer time, but not much) in AutoCAD and lower frame rates in Cities: Skylines (this game is very CPU demanding).
