You need to get the top for that DDC that has the one going out and one going up, that way you only have a 90 degree bend and not a 180, which will put some serious strain on your pump as well as temps. I think that either a large memory cooler attached to the side or a small 80/92mm rad would work. Might want to get a "U" based PSU or one of the M2ATX ones and put your rad there.
Ordered the mCubed Imon display from there store. Got it today. Dam thay are fast shipping and packaged very good. Now to wait for my other order from Proformace-pc. Should have it tomorrow I hope.
