Finally managed to complete my PC build and I went ahead and tried fitting the Antec 920 again and somehow managed to make it work...just!!
It is fairly amazing how much you can squeeze in such a small case.
Check out some pics:
And the mess in the back:
Took me forever to clear the cable clutter and manage everything. Also took a long time to figure out the best way to set up the Antec cooler so that firstly it fits and secondly the pipes don't bump into and put pressure on the GPU or the RAM or any other components.
Still have a few niggles with the case. There is a buzzing/humming noise coming from the top area where the USB, headphone jacks and all are. If you plug in your headphones, you end up hearing the buzzing in your headphones which is quite annoying and so I've ended up using the audio from my monitor via the HDMI coming from the GPU. Also found out the eSATA port on the top doesn't work on my case... So this is what I'm not really happy about with the case. But its still a brilliant little case!!
