CPU The core i3 works great for what i'm using it for (light gaming) and i didn't have any problems at all. it stays very cool
MOTHERBOARD Honestly just picked up the cheapest board from memory express. so far no problems. only complaint would be that you only have one fan header for your fan but you buy what you pay for.
MEMORY I just got the cheapest ram that memory express had in stock, nothing special just ram. so far no problems.
VIDEO CARD I am borrowing this from a friend. later i'm gonna upgrade to an rx 580. only complaint is that it gets very hot under load and it starts to thermal throttle.
CASE I just needed something that would hold pc parts. The case is really bad. The bottom pads fall off IMMEDIATELY after opening the box. This case is VERY cramped inside. on the bright side it did come with two fans, one of which was molex. Other than that, case was great.
PSU Again just got the cheapest one i could find on amazon. no problems, it supplies power. One thing i do want to say tho it that the fan is very quit.
OVERALL This build was just meant to get me into the pcmr, i wanted to stop gaming on my "crap-top" (get it) i was struggling a good 20-30 fps on every not very demanding game. (minecraft, terraria, roblox, overwatch) I am overall very excited to own this pc and im looking forward to my next upgrade come christmas.

EDIT I didnt get the rx 580 i was hoping for but i did get an rx570 and its been serving me great. my 500 dollar build somehow conspired to about 1000 dollars which is kinda crazy. i got the air 240 for Christmas and i bought all the new stuff with christmas money
Sorry my pictures are blurry
