Yes lol, the Reserator is an out-of-case deal. I do like all in the case, especially since i have a very large full tower (TT Armor<3). But out of case can be nice too. I've heard good things about Exos2's, but I know my custom kit will destroy that thing when it comes in a few days.
I am still using stock cooling.. I increased the PCIe x16 speeds on slot 1 to 125 in my BIOS, which allows much higher speeds (stable too
). It's very hot in my room (ambient around my case is 41C) and my card is hitting about 65C idle which isn;t good but then again this isn;t normal conditions. I'm sweating right here >< lol.
Honestly, my final word on the matter is a custom kit. Drop the $300 and get a good custom system. I will be taking pics and making a walk through on the installation of a custom system when i do mine in a week or so (I have a lot of case modding to do)
