I used the Thermaltake G41 Commander case but it is not listed on here. I probably went a little overboard on the CPU cooler but I went with it so it would be aesthetically pleasing. Although as a side note if you decide to go with this build I would recommend going with the G42 instead based off of the fact that the 240mm radiator fits a little closer to the motherboard than I would like. The only difference between the 41 and the 42 that I could find was the Front panels look slightly different and the 42 is 3 inches taller. Had no issues or conflicts with anything software or hardware wise. Although as another side note I had a small hiccup with the WD 1TB Black, For whatever reason it didn't want to show up in the files so I had to go into the manager to get it to show up. I absolutely love the ram and am planning on adding another 8GB for a total of 16GB (2x2 dual channel 8GB) The R9270 is a good choice and overclocks easily and stabily with ASUS GPU tweak. I am also planning on adding a second R9 270 for a two way crossfire configuration. The case as I said is A G41 commander and I absolutely love it, looks great with the large window (I chose the 41 over the 42 because I like the 41's front panel better) The power supply works well but I am planning on upgrading it to a at least a 750W to accommodate the second graphics card. Windows 8 is just fine. I love the monitor as well and am planning on getting a second when I get the second graphics card and new PSU. The 23.6 inches is awesome and looks amazing on all games I play. The network adapter I have not used but will use in the future. The fans are awesome fits great with the blue LED ram and the overall colour theme (Black and Blue) they are fairly quiet and do a good job of keeping the rig cool. The fan controller I have not yet received as it was on back order when I bought it but it will be here soon and I will edit this part accordingly. Keyboard is awesome and allows me to change the colour to match my system.I love the mouse as well, razor did a great job on this and if I had not already had the keyboard I would have most likely gotten a black widow ultimate chroma as well. Headphones work just fine. Great sound for both gaming and music. They are rectangular so it feels weird to take them off after a few hours of gaming ( They don't hurt it just feels weird after you take them off) Joystick I got several years ago and works great but was discontinued.
