I used some old memory and PSU for this build. Overall, it was a smooth build. The S340 is very easy to organize and build up. I did have a problem with one of the rear fans, but a little oil and that was fixed. I used Cougar 120mm fans for the front intake and PSU extension cables to hide the PSUs yellow, red, and black cables. The 24pin extension is NZXT and the PCI-E and 8pin 12v extensions are SilverStone. The tape on the LED strip peeled off after several hours so I had to hot glue the LED strip to the ceiling of the case.
