Additionally, it doesn't look like that case comes with any cooling fans. According to the specs, it has locations for a 90mm (rear) fan and an 80mm (front) fan. Definitely add these to your shipping list.
Also you selected a 'K" series CPU (for over clocking), but and H61 Motherboard (no overclocking) you need to change this (either to a non 'K' CPU or to a Z77 Motherboard) other wise you are wasting money.
if you go Z77 and 'K' series CPU you need to go with PC1600 Memory
if you actually go to the web page you will see that the B75 CPU overclocking is listed as "No' though it also list the H77 as a yes, and that is not true either. The Intel site hints at OCing for the B and H 77/75's, but the reality is that the only chipsets that will support OCing the CPU are P67,Z68, and Z77.
