Continuing...
I decided: chose RAD at the top of the case.
RAD above, VGA in place with the pump just below.

RAD where it will ultimately have with the fans (provisional). In the picture lacks the spacer (being prepared) that will keep fans of the 50mm case. Or a mounting kit by Swiftech, i thinking about. Because I have no much time off.

The reserv already ordered a Swiftech McRES rev2, I've had one of these and is very practical.
It allows the setting of various forms. Besides being able to opt out of the water bottom, or side.
Diagram (crude!) I made to illustrate the toilet, your hoses, etc to book.
Today I worked a little on the case at lunch...
I made several cuts, all in Jigsaws Bosch. I opened the window on the left side (I forgot to take pictures).
I wanted to put a 120mm fan at the rear. Lack of space 3 mm (width only).
But I would be strange, it would be left "parts" of the small panel back, as the 120mm fan would occupy more central area of the rear panel there. would require another MOD, covering the entire back panel (the location of the fan) with an acrylic, for example... did this in Chieftec CX-01 in 3 fans the right side, which cool the hard drives.
As below:

Thus, to avoid a hassle, which may need more time, which is scarce. Preferred to keep 2 fans 80mm even only removed the mesh.
Grills placed only for the photos, the screws will be others etc ...

Every case that I modified to date, installed wheels. As I always say, I like to functional changes. These wheels think they are always helpful. "On the Road".
Detail:It's is a PSU Dummy, for testing equipment, which has the same length as the Corsair to be used. There will only be 1 HD more. See the final position of the pump as well.
I opened space for 92mm fan:

My hacksaw in action (I haven't Dremel), opening a window on the right side.
I wanted to open a larger window yet, but there are details on the back of the side that could not cut because they are part of the trail that lay on the case.
I had set the location of the RAD, and was elected to the top.
I wanted to put the fittings facing the front of the case and the hoses going inside it, through holes for them.
But, where the hoses enter, it would be just where is the support for 2x drives, and move to the cables from the source.
Thus, the place was completely filled, and there is no other place to install the hard drives.
On the back of the case also tried the RAD. Several people suggested this place, inclusive.
But RAD is almost the same width as the case, so not to block the passage of cables on the back plate I/O, power etc. The RAD should be a least 150mm away from the back of the case.
I tried, but I thought it would be very strange visual and practical too. There would be no usual, the RAD there, either remove and install cables .... I gave up.
Assembled on site in short (missed finishing, parts cleaning, etc. ...)

Overview of the interior, with the fans installed, Rad site etc ...

More details of 2x fans 80mmm who acted as exhaust, along with the 120mm of the PSU.
Already sleeve all cables, to improve the visual / internal organization.

I still have problem to install my baybus, which is a Zalman MFC1 modified by me. I used it with my last 3 cases (large!).

But in this case small, is difficult to find a place for him. Maybe put in top roof a little ahead of the RAD. Thus it would be the cables hidden, not disturbing the visual.
I made a drawing (crude!) In the paint, only go to illustrate what he said:

Well, latter I want to find some time to reach solutions where to install baybus, what shall I do with the cables of a USB / Firewire Audio and front, and others more.
Hugs and thanks!
