Hi there,

I have a custom built tower with the following components

Motherboard: Gigabyte B85M-HD3
RAM - 2 x 4GB sticks
CPU - i5 3ghz
Graphics card - nVidia GTX 950
HDD 1 - 120gb ssd
HDD 2 - 1tb 3.5" Sata3
Power Supply - This is old so would be happy to change

I currently have a full-size tower which is becoming a bit of an annoyance due to it's sheer size. There seems to be a lot of empty space in the case which makes me think the possibility would be there to downsize a little.I don't want to replace too many of the parts to keep it as cheap as possible.

Before I go out and buy something smaller, I'm just wondering if anybody has any specific recommendations or tips on what to look for/avoid?

EDIT:
My current box is 500x450x200mm
I had something like this in mind
