Value rig with room for upgrades

[mightychieftain]

Hey all, threw this together fairly quickly and tried to keep it on the inexpensive side as I just got myself a laptop. Nothing special compared to some of the beasts I've seen on here, but let me know how you think I did with performance at a value.

Z87-G41 PC Mate Socket LGA 1150 ATX Intel Motherboard
Core i3 4340 3.6GHz LGA 1150 Boxed Processor
MSI R9 270 GAMING 2GB 256-Bit GDDR5 HDCP Ready CrossFireX

I got the rest from work for free, which is half the reason I decided to throw a build together:
4x 4gb DDR3 RAM, 2x 7000rpm 500gb HDDs, and a 520w PSU

I went with that mobo+cpu combo because they were pretty cheap and the LGA 1150 on the mobo will allow me to upgrade to the future next gen intel CPU (which I will be able to save up for and splurge on). I plan on adding an SSD soon and memory upgrades as the deals come across. I'm at work now so I can't post pics, but I ended up getting some crappy $40 case and adding 2 additional fans for cooling.

I'm open to criticism/upgrade suggestions since this is my first build, just try not to be a dick about it
