Eto mga options mo:
1. Presumably na full pc build yan at included sa 40k ung peripherals like monitor, keyboard, mouse, headphones/headset or speaker at monitor - mabibibitin ka sa budget nyan. It will be an low-entry-level pc build without future proof yan. Ofc, with generic brands or not-known hardwares lang ang maafford mo.
2. If CPU lang talaga then you need to think kung ano purpose mo for that PC and you always put in your mind na 40k lang budget mo - i really dont know anu pricing ngaun jan sa pinas but here in UAE around 2.5k aed yan into conversion which is for me entry level (na may low-end gpu) lang din ang mabuibuild ko sa budget na yan. And which is unfortunately kapresyo nyan isang GPU lang na either 5070 or 9070 xt kung sale.
3. If di ka naman din techy at di ka willing mag upgrade - go for the laptop nalang.
4. Or postpone mo muna then dagdagan mo pa budget mo kahit umabot ka lang sa mid-level setup. around 60 to 70k (around 4.4k aed) same budget nung nag build ako ng mid-level pc para sa kapatid ko.
