Piliin mo yung most/almost recently released cpu ng AMD. If not, mag intel ka nalang, medyo bad yung previous/older releases ng AMD. Almost any brand ng motherboard Okay na ngayon, Gigabyte(Aorus)/MSI/Zotac/Asus etc...
Sa GPU naman pwede budget kaso talo ka sa GPU fans, suggest ko mag invest ka para sa good quality GPU, sa Zotac much better kung AMP! version, the rest of your choice is MSI/ASUS. Gigabyte GPU not sure pa if maganda.
For RAM go for 3000Mhz and above kahit 1 stick 8GB lang muna basta may RAM kasi bibili ka pa other external devices such as monitors and control devices.
Power supply around 500w pwede na if hindi ka mag overclock.
Any pc case with good ventilation is a must if hindi aircon ang room.
RGB is optional, pick performance wise products.
