16GB single stick DDR4 is quite rare in Malaysia so just for go for 8GB x 2.

Keyboard selection is too subjective, you can opt for cheaper Ducky brand to reduce cost if you wish.

Speaker isn't included as there are too many options out there, 2.1, 5.1, 7.1 etc.

On-board sound card is sufficient for normal user unless you are an audiophile, cheap dedicated sound card isn't going to give you significant sound quality improvement so just stay with on-board sound card for the time being and buy a high end one when you need it/have money to buy in the future.

Since you are coming from laptop, most likely you need WiFi card unless you are going for wired connection, you can add one if needed (TP-LINK TL-WN881ND, RM 58).

Risky? You cannot even touch 600W on a non-oc setup, the max draw is around 400 - 450W only during load.

Seasonic 620W is enough for GTX980Ti.

If you want 800W 80+ Gold then you gonna downgrade other parts.

And you said the keyboard can remove? Do you mean you don't need the MKB anymore? If yes then the funds can be used to cover up the cost for a 80+ Gold PSU like CM V750 or Corsair RM750x etc.

Nvidia website stated that as recommended.

600~620 watts power supply is more than enough for 980Ti

800~850 watts is more than enough for SLi setup of 980Ti's
