What computer should I buy for light/moderate gaming?

I'm looking for a PC to buy for light/moderate gaming. I want to start making YouTube videos. I want to play minecraft and stuff on steam. I don't want to spend a lot since I have a MacBook Pro for editing.
I want the pc because I have the baseline MacBook and can only upgrade the ram and HDD.
The PC will also need a hdmi out because I will record with elgaro and have hdmi monitors.
The Mac will be used for recording the PC as we'll

Bestbuy.com is really good at sorting computers out based on your needs. Sorry I couldn't be more help.

The problem is that the cpu fan need cleaning. You had the same problem

Assemble a computer yourself. Its just like putting together a tv stand from walmart (actually A LOT easier lol)

i3-4130
any cheap H81 chipset motherboard
8GB of ram (4GBx2) ddr3-1600
1-2TB 7200rpm hdd
r7 260X graphics card
corsair cx430 or cx500 (430 is more then enough for this build, 500 would allow more room for upgrades)
nzxt 210 case (maybe add a 120mm fan at the front as an intake)

dvd drives arnt really needed, just install windows from a usb flash drive.
