lol peripherals are so subjective.
mech keyboard: budget - go for tecware. if budget not an issue, can consider razer huntsman te. otherwise, coolermaster/hyperx fits nicely in between tecware and razer in terms of budget.
mouse: what is your grip style. smaller mice usually better for fps. mm711 now is only 79.90 on lazada. wireless no longer have input lag, so it's comparable to wired. just go google around, all popular mice brands are available locally such as glorious, razer, coolermaster, logitech, steelseries etc.
sorry, i'm too lazy to format my points into sentences but it should be understandable lol.
