Best place to look is at Plaza Lowyat. Right now finding any stock online for any RTX 30 series is borderline impossible and even if they were, prices are jacked up.

They do sell some bundle deals there and if you look around and talk to people you may be lucky to find a decent build for RM4000. I think you may be able to get a R7 3700x + RTX 3060 for around RM4000.
