I plan on using this as a triple boot setup to run windows, steamOS and maybe hackintosh. I went for the most efficient setup that could still run the latest titles. Will add updates after some benchmarking. With this build my goal was a small & quiet gaming rig.
CPU: I went with the Core i7 4790S as it only draws 65watts, enabling a cool and quiet setup. Got a good deal at Microcenter.
Video Card: Amazing video card, super fast, runs cool all at a great price. I picked this up at newegg when the free game deal was going on. Only drawback is the card is soo heavy it causes the motherboard to sag a bit under the PCIE side. I was able to mitigate this by tucking part of a power cord under this part of the motherboard to hold it up better. The sagging is minimal though.
MOBO: Good Z97 for the price, not necessarily flashy but built well and is future proofed to work with the upcoming broadwell 14nm chips. Only complaint is the blue heat-sink doesn't match the rest of my build. Got this on newegg.
Ram: Love this ram, most efficient quality ram out there. Low profile, aggressive timings and only needs 1.35 volts. Plus it can overclock up to 2133 if I ever need it to. Got this on Tigerdirect.
Liquid cooler: Picked this corsair H100i refurbished from Newegg for a great price, keeps my cpu 27c at idle and is absolutely silent with the SP120 quiets I added to it.
Case: The Corsair 250d is the best HTPC i could find to suit my needs. Picked this up on Amazon.
Power Supply: Efficiently supplies the perfect amount of power for this setup, anymore would have been overkill/waste IMO since this setup only draws ~300 watts. Got this on newegg.
Monitor: This ASUS monitor is amazing, 144hz @ 1080P is perfect. Got this on Tigerdirect.
Keyboard: My first real mechanical gaming keyboard, it makes gaming more enjoyable. Got this at Frys.
Case Fan: Replaced the front fan with the quiet edition. Got this on tigerdirect.
Optical drive: Already had this Bluray Burner from my last build
Windows: Already had this from a while back.
SSD & HDD: Had both of these in my last build.
Mouse: Had this already.
