Only vendor price of your case in USD ($), without extras like water cooling, radiators, extra fans or extra side panels etc.
Obviously this applies only to those who built their own PCs.
I'm just curious what people are willing to spend on computer cases. Mine did cost like 300 EUR when I bought it a few years ago, now it's much cheaper: Silverstone TJ-10
I guess my next one will be a self made case, I have to try that at least once
Currently, for me the most fascinating case on the market is the InWin H-Frame. Weird design, it will eat a lot of dust but it looks special and is all aluminum. Unfortunately it cannot handle E-ATX.
