CPU - You spend so much on a K-SERIES chip, you better be sure you're planning to overclock it. Dont buy just cuz of the hype.
MOBO - Pure
garbage. Why TF u spend so much on a powerful chip but no proper overclocking board? You rlly got me triggered there.
COOLING - Go big on watercooling at LEAST 240mm, or go fan. That 120 AS watercooling is crappier than a good-sized NOCTUA fan cooler and more expensive. Again, your pricing is horrendous, your choice of that watercooling is ****.
OS - Unless youre some OS purist and only want retail version, there's loads of grey-market copies of win10 OS out there on carousell, kinguin for 10-40SGD. Why pay 120SGD for OS?
SSD - 512 SATA SSD on m.2 slot == wasting the m.2 slot. M.2 slot is for NVME(3-4x faster than SATA for large file xfers) not to mention you can get a good CRUCIAL NVME m.2 SSD for cheaper outside. Again, stupid choice to put a SATA SSD into the m.2 slot. If can, leave the slot empty and buy ur own NVME SSD outside
You wanted roasting, so i be as crude as possible
You want a cheaper but just as powerful alternative, I'd go with a 2700x build instead. 8c/8T of 9700k vs 8c/16T of 2700x
