What component should I buy next?

[ModernKamikaze]

I already have the CPU (i3-2120) and the motherboard (ASUS P8H61-M LX), what should I buy next?

From first to last, which component should I buy next?

Please give me in order so I can readily purchase those components when I go next time in my store.

RAM
PSU
HDD
Case

and as always, thank you for those who help!

Case + PSU

HDD + RAM

CPU + mobo

If you buy with gaps between thats the usual order reason being its the order things are likely to not go obsolete.
