I had started building this machine in early August 2013. At the time, I had picked up the CPU, Cooler, Motherboard, Memory, Storage, Video Card and Operating system. The cooler and video card both had a $30 rebates. The case I wanted to use for the build had not been released yet, so I had stuffed the parts into an ugly old case with a spare 450 watt Enermax Noisetaker to power it. The keyboard I had received from my wife as a Christmas present and the mouse I had gotten for $25 with money I had earned on AppTrailers. I had finally received the case in mid to late February as well as the SFX power supply and modular cable set for it.
For CD-ROM and DVD usage, I have an external USB drive that I normally use for my netbook. I also have 2 3tb external hard drives for backup duty as well as media storage.
About 2 weeks was spent trying to figure out the best way to orient the parts in the case to maximize airflow in the case; outside of working full-time. Luckily due to the length of my video card, I was able to fit the radiator in the front compartment of the case. Originally I had used one of the included Silverstone fans, but the max temps rose to around 90 degrees Celsius using a program called Heavyload. I ended up using the one that is included with the water cooler and the temperature now maxes out at around 70 degrees Celsius. I am not overly fond of the fan as it makes a small ticking noise at low rpm. I am thinking about replacing that in the near future. Under normal gaming usage the CPU temperature is around 50 degrees Celsius. The motherboard temperatures barely ever budge from idle to full at around 45 degrees Celsius.
For future upgrades, I will eventually plan on getting a SSD drive. Currently what I am doing is using 6 Gigs of RAM in the system as a RAM Drive using the Radeon RAMDisk program and another program called Ready Cache to treat it as a caching drive. The end result performance right around SSD speeds upon multiple times loading a program.
Update 5/6/14 - Since the radiator fan that came with my Seidon started developing a loud clicking noise, I purchased a Corsair Air Series SP120 Quiet Edition fan. Since this came in a twin pack, I am using the second fan under the video card to help with cooling. I have also finally picked up a 256gb San Disk SSD drive due to a shell shocker offer on NewEgg. Cloning the OS was a pain as I had to backup over a terabyte of data to external hard drives to be able to do it. I used EaseUS Todo Backup for the cloning program.
