I tried searching for nicer cases to accommodate EVERYTHING I have, but no avail. Like I showed you, I couldn't find a case which supported 4x USB 2.0, 4x USB 3.0, 1 HDMI, and a 8-in-1 card reader.
As for the GTX 650 TI, I got that because of the price and the reviews I saw on youtube for it. Many people were able to play games on high or even ultra, so that is pretty good. Guess it really depends on the particular game.
