Nice. Well then I'll start by recommending Asus for a motherboard manufacturer. Yes there are alternatives, and yes the alternatives can work just as well, but after ~10 years of being in the computer repair field, I can safely say that Asus has a leg up vs other manufacturers. Good stuff. Also found in many HP and Alienware machines just re-badged 😉
Same for the GSkill brand of memory, though I'm a little less attached to them. I did see my first ever failed memory stick of that brand last week though. Crucial, Kingston, Mushkin, Samsung, all are good brands of memory though fairly speaking.
For a CPU, just get something you can afford...lol
Power supply, any "80+" certified unit is good, I highly recommend the Seasonic brand, but Thermaltake and others are fine too. Just make sure it can drive everything you have.
GPU....again, whatever you can afford.
For OS drive, I highly recommend Samsung SSDs, highly discourage buying A-Data SSDs. Other major brands are fine, but I've been selling Samsung to my customers for years and I've only ever had one to fail and it was physically damaged somehow. If your board has the option for a NVMe or m.2 then definitely go that route.
For storage, definitely recommend Western Digital. Anything works, I've just seen long life and reliability from the WD drives.
I think thats about everything....all the high points anyway ^.^
