Planning a hackintosh build for this summer. I work on a mac and i dont mind the OS, being a frequent linux user, I just absolutely despise purchasing anything with that darn apple on it and paying the big bucks. I have read a few hardware guides and have picked out some hardware (low budget build). I dont have question that it will work seeing as its a pre-made guide and people have already had success with the build.

Like I said this is just a low budget build, nothing fancy so I am only planning an i5, 8GB ram, and an EVGA Geforce GT 640 2GB graphics card for the dual monitor support and mild graphics. Like I said nothing fancy.

My design is going to be a hackintosh build in a server case so I can mount it in my server rack next to my desk. See link for server case.

With this server rack I have decided since it has that middle fan mount/support bar that i am going to water cool and mount the rad there pulling air from the front of the box back through. I water cooled my current gaming rig's cpu and I love it, I just dont ever want to air cool a cpu ever again.

GT640:EVGA 02G-P4-2645-KR GeForce GT 640 2GB 128-bit DDR3 PCI Express 3.0 x16 HDCP Ready Video Card -

My question is has anyone ever water cooled an EVGA GT640 with just a generic VGA waterblock? I plan to water cool it also since I wont have extreme amounts of heat coming off the i5 however I dont want to hear the cooler fan on this thing spin up to cut down on a little fan noise (using quiet fans in the rest of the system). It wont cost me much more to add the VGA waterblock to the cost of water cooling the system.

Any suggestions? Also this is not my first custom build nor my first water cool project.
