Tunic Tower 120
 

The provided fan is annoying, ball bearing noisy but thankfully it's
upgradable. However, so are Scythe heatsinks, the Noctua NH-U12 and the
CoolerMaster Gemini from off the top of my head. I'm sure there are a
few more, and these don't have the same 25mm depth restriction. In
addition, for £33 I'd expect an awesome fan to come with it in the first
place, and while it is "nine bladed for better performance" perhaps a
sleeve bearing would be more appropriate?
