Looks nice and clean. I also recommend ditching the loopdy-loop thing coming off of the video card. I would try making the length of hose between the T for the fill tube and the pump inlet a lot shorter. There's no reason not to have the plastic of the T and the plastic of the pump inlet barb physically touching eachother. This would also virtually eliminate two size changes in the plumbing where the water has to do some acrobatics to keep flowing, which should theoretically make the water flow around the loop with a little greater ease.

If shortening that section of tubing to nothing still isn;t enough to get a reasonable curve off of the video card block, I would slide the pump further forward. It looks like you have about a half-inch of space before the pump would run into that drive cage. Heck; you could even raise the pump up a bit with a scrap of wood or a bracked fabricated of sheet metal and stick the butt-end of the pump inside the opening of the drive cage for even more room. If you do this, I would highly recommend using some kind of vibration-dampening material like a block of soft rubber to offset the pump. No reason not to make things quieter and kill some vibration in the process, right?
