I will add some better pictures in the next few weeks, very bust with school at the moment
This is a build I did for my roommate last fall. He was looking for a relatively cheap computer to circumvent buying a new console. As I was looking to upgrade my existing rig already, it gave me an opportunity to find a home for my PSU and R9 270X (Excluding the OS, he payed me $600 to get parts, so I didn't lose much on what I had originally payed for the parts I put into this thing + building computers is fun). He wasn't really interested in overclocking or having to upgrade hardware down the road, so I tried to keep the build simple while giving him a solid foundation for the next 5-10 years.
A few bumps in the road, such as the motherboard turning on the onboard graphics by default and cable management mayhem, but otherwise it has worked very smoothly for him. I didn't get a chance to test anything or record temperatures, but everything is at stock speeds.
CPU (Intel Core i3-4150): I wanted to go with the Pentium G3258 but settled for this chip. Essentially, more expensive but lower maintenance. Relatively swift chip. Not much else to say.
Motherboard (Gigabyte GA-B85N Pheonix): I'm not sure who this board is designed for but it was one of the cheaper mini-itx boards with onboard wifi that I could find at a more budget oriented-price. The orange LEDs are really random (especially on a business-grade mobo) but kinda cool. Had some weird defaults in the BIOS, but I think that's the case with every board so no harm, no fowl.
RAM (G. Skill Ripjams 4GB): Skimped a little here to save him some money. Only having 4 GB hasn't caused him too many issues as he really doesn't do anything too RAM intensive. It's the only thing in this build he would really ever need to upgrade and is relatively simple to do. So I thought it was a fair trade-off.
Video Card (Sapphire Radeon R9 270X): This was a used part from my rig. Both of us have actually been very impressed with this card. He has a 1080p 60Hz monitor and that seems to be this cards sweetspot. Because of its location in the case, it gets plenty of fresh air and doesn't seem to get too hot.
Case (Cooler Master Elite 130): You are doing yourself a favor by getting at least a semi-modular PSU if you plan on building in this case. Cable management was definitely a challenge, but once it was set and done the build looked very cozy in this case. If your using air cooling: a) the PSU is directly over the CPU so tall cooling blocks will not fit. b) be sure to allow for good air flow throughout the case so that the temps don't get too high under load (even idle, 45-50 degrees C, was a too high prior to fixing the cable management). All of this aside, the case looks nice and takes up very little space.
PSU (Antec EarthWatts Platinum 550W ): Also a part from my original rig. More Watts than I needed for this build but nice and efficient (he does tend to leave it on 24/7), although it probably isn't making that big of a dent in our electricity bill anyway (:P). The biggest problem with this was that it was non-modular and hiding what was a majority of the unused cables was a *. Otherwise it works well and saved the trouble of ordering a new part altogether.
While the building process itself was a bit of a challenge, ultimately we've been impressed with how well this computer handles games.
