Please Help with my PC Build!

Samsung 840 Series 120GB 2.5 inch SATA Solid State Drive

I3 3220          

Asus P8H61-MX R2.0

8gb of DDR3 RAM

Asus Radeon HD 7770

I do know their are some parts missing, for example the case (by the way, does anyone know what a good case would be to buy?). Can someone please tell me if this build is good or bad...and if they have any improvements i could make. Please consider that this build is a "budget" build, but i intend this build to be a replacement for my console, so I would like it to have decent specs :)

Thanks :)


What is your budget?

£500-£600 :)

I want some money left over for a good monitor etc. :)
