To me, personally, I think your results with the non-case option are a work of art as well as having valid scientific advantages of not having a case. It looks alot like a modern version of the breadboards we produced back on our Commercial wheat & cattle operation in the early to mid 1970's that Waz and Cousin Billy used to come out and look at.
The advantages as I see them are being able to keep an eye, and in some cases... no pun(s) intended, an ear on your PC.
If I had that in my house, the wife's cats would have it wrecked in about 15 minutes, so it doesn't work for me in my present situation.
This thread kinda comes down to the whole respect for the other guy thing. Who am I to say that custom water cooling the way I do it is "the" way to go for all people? Who's to say air cooling or anything else is not as valid as the solution I come up with? All I can do is show what I've done and what I've seen and what people reort in general is the result. Deciding what is right for you is NOT my job and I have plenty to do just keeping up with my own decisions.
