I'm building another computer, and I thought I'd try something slightly different. In this thread I'll try to explain how I go about building a "Concept Computer", as I'm calling it. When finished, I'll give it another name.
I start out with a number of things that I'll fit into the concept. Size is first....this computer will sit under a desk, in front of a cabinet, so I'm limited by the height/width/depth of this space. Luckily I have several new Gateway cases that I think will fit into the space, and will have the potential to be modded into the concept.
I'll use a P4-3.4 NW, because I have one and like it's performance potential, and have already had experience dealing with the heat. The MB is optional...I have several that I could use, but I'm trying out a new Biostar. This is subject to change, if I'm not satisfied with the initial testing.
This will be a positive pressure case, with the intake/s filtered. Since the space at the rear of the computer is limited, the filter/s cannot be at the rear......just not enough space for a big enough filter. I have several new ideas I will work on for this problem.....not there yet. There will be no openings at the front of the computer.....period.
For a PSU I'll use a Fortron Zen......totally noiseless, with enough power (300w). Since this PSU has no fan of it's own, I must design the airflow of the case to help cool the Zen, which will be at the top of the case.
First thing to do....mod a Zalman 7700 with a Yate Loon 120mm fan. I think this heatsink will work great with the concept. Here's a few photos.
The round aluminum disk is epoxied to the stock Zalman bracket.....the cut-up Yate Loon is attached to the disk by 3M double-sided foam tape, about 1mm thick. This effectively de-couples the fan from the heatsink....works very well. Now is the time to test out this new board, and the HSF. And I do it on a desk.....no sense wasting time with the case right now. If the board performs to my liking, then I'll install it in the case. I also do temperature testing at this time.....
I'm also trying out a new HD cooler....A SYBA model, with heatpipes and a heatsink on the top-side. The bottom is open. For testing I'm using an older Samsung drive.....will be changed later.
At this point I'll run the thing as you see it, install some programs, maybe try a video card, do temp benchmarking, try out a fan control system....no hurry here. I want to be certain this board will be satisfactory. More to come......
