Is a fan on the case mandatory for a Gaming PC?
When I built my PC I didnt order a new case, I just used the old one I had.
My Setup is the following:
CPU - AMD Phenom II X4 965 Black Edition
GPU - Sapphire HD 7770 OC
Mobo - MSI 760GM-E51 (FX)
PSU - OCZ 500W CoreXSTream 2
RAM - 2x DDR3 4GB Kingston, 1333MHz
Heatsink - Arctic-Cooling Freezer 13
Now, as my setup is not up-to-date anymore, I've been thinking about what I should upgrade first, CPU or GPU, or maybe buy a new case?

Then I figured I don't have any fans on the case, only the PSU Fan. Inside I only have the CPU Heatsink and the GPU Fan.
Temperatures are ok, I only bought the Freezer 13 because the stock heatsink was too loud.
Currently, I have a game open, a few programs running in the background and a bunch of Chrome tabs open (my current Airflow research) and the temperatures are the following: (according to Aida64)

Motherboard - 39C (102F)
CPU - 36C (97F)
CPU Cores 1 to 4 - each at 50C (122F)
GPU - 41C (106F)

Would an 'upgrade' to a better case give a significant decrease in temperature and would it allow me to overclock my CPU (thats why I bought the 965 Black Edition) from 3400 Mhz to at least 3800 Mhz?
Which Cases would you recommend?

Fans are definitely mandatory, and they are very cheap to buy, too. Front and bottom fans are intake fans, or they bring in air. Top and rear fans are exhaust, or they blow air out. Without airflow from fans, any PC will get way too hot which affects performance and lifetime of the parts. You can check your case specifications to see what sized fans it supports (usually 120mm or 140mm). You should but at least 3 fans, and if you have an odd number, make the intake fans more powerful than the exhaust.

Edit: You should always post your temps in Celcius

I don't see any free spots where the fans could be placed, eventually on the side panels.

EDIT: My case is a old ASUS Fan that once belonged to a normal desktop PC.
I took everything out and built my new PC into it. I believe it is at least 10 years old and doesnt have a Model number I could check up to what Fan sizes it supports.

Just took a picture of the front:

All I have on the back is the back of the Power Supply, Motherboard and GPU in/outputs and a few grids. Even though there is no slot for it, a small fan could be mounted to the back, but it would lay a bit over the middle of the case.
The front has no options for a fan.
