After 3 years of using a MacPro booted into Windows 7 through Bootcamp I was ready to build my first PC (hence the slightly-flashy case!). After some research and initially thinking of a cheaper build using an AMD CPU I went down this route with the i5-4670k to allow for a little bit more future flexibility and over-clocking options.
It's been a fantastic learning experience and most importantly I've realised certain aspects to building a PC that my research totally missed - space for cable management (not enough in the LEXA!), and the limit on SATA devices imposed by PSU and Motherboard connections.
Stock cooler and 430W PSU as I'm not intending to start overclocking yet.
It's a PC built for general use with a very large toe dipped into gaming waters. As far as my general use goes the first update to the build will be to at least double the memory, if not adding an additional 16GB. And for gaming the 7850 has been a great choice to start with, running most games at a native 1080p with settings on High or Ultra.
Additional notes: I've added all the drives that I already had but have installed in the case and it was a Pioneer DVR121LBK that I purchased and not the Samsung listed. All parts were purchases from Scan as I wasn't quite so price-sensitive and much preferred everything being delivered at once. Other than cable management I had no build problems (even for a first time), and although it didn't boot on first attempt at power-up re-plugging both the main motherboard power connection and the front panel connections resolved whatever wasn't connected correctly.
PS. Machine was completed early December 2013, totally loved it since. Long live the Master Race!
