The N450 is an amazing case - there was plenty of room for everything. I opted for a red/black theme, so I tried to keep everything within that color scheme. I like how there is a shroud that hides the power supply, and you can actually mount two SSDs on top of the shroud. The case also comes with an awesome looking underglow and I/O panel illumination. I ran the NZXT lighting kit through the case and also mounted the NZXT red case fan to give it illumination from the inside.
I was able to overclock the processor to 4.8ghz with no effort using the ASUS built in overclocking tools (I'm going to try and push it to at least 5ghz) and the two graphics cards were also easily overclocked w/ EVGA PrecisionX. Originally, I tried to 2-way SLI a 970 FTW and a 970 FTW+...however these two cards are not SLI compatible...so I opted for a second FTW+. The power supply and liquid cooler both support Corsair Link, which is pretty cool.
