Only go prebuilt OEM PC when your budget is low, this 2.2k build is a pure rip off with i5 and a non useful GT730, even the iGPU is better than this dedicated GPU, I don't see the point to slot in GT730 in this build TBH unless you want Nvidia's CUDA technology for your operation.

What games and settings you are looking to run? Is video editing the main task for the rig? How you define good sound system? Are you an audiophile? If yes then you need a high end sound card which can cost nearly 1k FYI.

I would recommend Windows 10 over 7/8.1 anytime, it is great and I have zero complaint on it since the first day I use it.

So your budget is at least 2k? Any maximum limit?

If I recall correctly, ETech will install Windows 10 for you, some of the forumers here commented they are giving the key for free, it might be too good to be true, you can ask them directly via their FB page/lelong account etc.

I bought 3 basic pc from etech and they all assemble and install ori win10 free. i checked it using cmd and confirm its legit win10.
i think he got cheap windows 7 from somewhere in upgrade to win10, coz on some of the pc it had a downgrade option, i already ask him if he got from this guy form lelong for RM35 but he said no.
the win10 they install is messy, you need to change the region , time etc.... they did not have time to do all that for you, and also you need to do a huge windows update, which took me like 6 hours each pc.

here is an alternative built, based on what you said it just seems you are a casual user, you dont really do a lot of pro vid/photo editing, just basic youtube stuff, and slight gaming

Basically downgrade your CPU and mobo -RM380, as you dont really need the raw power for you usage
downgraded your case -RM100 there are many cheaper case to choose from if you dont mid the looks
downgrade to USB wireless, if your wifi is close to your PC.

use the extra money to upgrade the following:
get an extra ssd for your OS, you will feel a world of difference, highly recommended
get a better speakers, may to choose form, ok ones start from RM100, there are plenty of good ones around RM200
my personal choice would be the bookshelf (R1000T IIII) its big tho, it also sounds better then the 2.1 at similar price range.
for speakers just stick to Edifier, its very good value.

if you intend to play games its better you get i3+gtx950 rather then a i5+gtx750ti, its provides better gaming performance and slightly cheaper too.
if you dont intend to play that much games just stick with gtx750ti and save yourself RM200, which is enought to play games at hd
