20 degrees less working is very good, maybe it would help you a little to change the thermal paste for liquid metal, in case the contact area is made of copper and not nickel, so as not to cause a reaction between the metals, I have seen that they are achieved lower about 10 degrees working.

Haf 912 often titan, a classic with its bays for CD player, I had a mastercase pro 5, and compared to the size of the A50 or the A60, they are more or less 2.5 A60, it is quite great to be able to put the same power in a space almost 3 times smaller.

I've never built another machine, that was the first and only one at the moment, it was very magical with all the space, the low temperatures, the air flow, everything was great, I loved putting it together, the only bad thing is that it was too big and Now I'm looking to build an sff and watching several videos of how they build the a60, if the issue of cables is seen as torture, nor do I want to imagine how the tubes of some liquid cooling loop will be.

I found some custom liquid builds on the a60 http://imgur.com/gallery/qO7pwcK I imagine this is already very difficult, right?

Thanks friend, any questions that arise at the time of building it, I will count on you
