I just put together the following for myself. it is completely silent at all times and runs very nicely..
Case: coolermaster silencio 650 (hence the silence)
Motherboard: ASRock Z87 PRO4
CPU: Intel i5-4670K (sweet spot for performance/dollar)
Memory: G.SKILL Sniper 8GB DDR3 2133MHz
GPU: Used my existing geforce 660
System drive: samsung ssd
hard drive 1TB wb black
very well put together PC, performance should be really high,
just a few observations,
this PC could easily work well with a decent quality 430W PSU from corsair,
if the user have no interest in overclocking it's possible to use a cheaper MB without loosing performance* (based on H81/B85/H87) or essential features.
also can get the non K CPU, the 4570 look like a very well balanced choice for people with no interest in OC, also if there is a price difference between memory speed, as long as your are not using integrated graphics using DDR3 1600 or 2133 is not going to make a significant difference,
*with H81 you are forced to PCIE 2.0 mode for the VGA, which in reality is not going to change anything in a visible way, also you have less sata/usb ports, less options for PCIE usage and multiple VGAs, and other differences in terms of RAID operation and such, but for most users all of this is not really necessary.
(not being negative about your build, it's VERY GOOD, just mentioning some possibilities of saving some money, since I love this game of building PCs with a low budget and reading about the new parts and technology)
let me mention some combinations of CPU and MB I find specially awesome in terms performance per money invested for gaming and typical usage if you think the i5 price is to high:
i3 4130 + H81 motherboard
and Athlon X4 760K + A75 FM2 board.
