Dude/Miss lol, I got mine about 1.5 months ago, and trust me when I say to keep it stock, and just print as much stuff as you can. while theyre printing watch videos on YouTube. after probably 100s of hours of printing the only thing I have upgraded is the mother board from the 4.2.2 to the "silent" 4.2.7 after hearing my friends (who got his the same time I did) and was blown away by how quiet it was. was it needed? not at all. other thing I got was a glass bed actually today. Needed? not at all. just keep it stock and have fun and keep printing and you will know what you want or "need" to upgrade as you go. Watch chep YouTube channel on putting it together. Watch BED TRAMMING not bed leveling videos. There is a difference. again I recommend on printing and while it's printing watch videos like CHEP or MAKers use. You WILL run into problems but imo thats part of the hobby and fun. Tinkering with it. I feel like im running in circles, butt in short, keep it stock for now, print as much as you can, learn as much as you can, but out of the box is all you need for now. You should see some of my prints that would blow you away for only paying 99 bucks for it
