Saw this at the Xiaomi shop. Is it a decent build?
Let's see
Ryzen 5 5600:
$190 on Amazon SG, I personally will not pay extra for the 5600x.
Decent B550M with Wifi:
MSI B550M PRO-VDH about $200 on Shopee
SE-226XT RGB:
$55 on shopee, though you can get away with the box cooler.
Corsair Vengence RGB pro SL DDR4 3200:
$103 on Shopee. Again RGB tax. Better RAM like the Vegeance DDR4 3600 are $95.
RTX 3060 local stock: anywhere from
$489 Zotac.
Galax model is $524 sold by PCKaki.
MTE220s 1TB:
$124 on Shopee
PSU: 750W 80+ Gold PSUs,
$110 Superflower semi modular
Case: Much better case Fractal Design Pop Mini Air $150, if you want cheap then Montech/Tecware stuff are $50.
Total: $1431
Of course you will be paying anywhere from $100 to $200 extra. If you DIY some parts will have longer warranty, but you have to build and troubleshoot yourself.
