Project CURV3D: Hardware and case

I have always been very passionate about small form factor builds so it felt natural for me to build a case as small as possible while trying to maintain a clean design. The challenge will be to fit powerful hardware in this case due to two reasons, the size and the heat. I had to choose very specific hardware that would fit.

Motherboard: Asrock FM2A88X-ITX+
CPU: AMD A10-7870K
Memory: Corsair Dominator Platinum 2x4GB DDR3 2400MHz
SSD: Corsair Force LX
PSU: Streacom Pico-PSU
Cooler: Corsair Hydro H75

So this build will be based on AMD’s A10-7870K because there will not fit a separate graphics card in the case so I want to have a CPU with very powerful integrated graphics. To power that I will be using a Pico-PSU which is a very small powersupply which uses a external powerbrick. To cool the CPU our H75 will be installed which will make this one of the smalles liquidcooled PC’s.

So after choosing hardware it is time to start working on the case itself. As I built this case years ago the basic shape and structure is already done, but I will be modifying it to be able to have better airflow etc.

This case is built up by two bent 8mm acrylic sheets, they are held together by two hinges, making it possible to open the case very simple.

Before there were only one hole for a 100mm fan in the bottom, which had to change so what I did was to measure out a hole for two 120mm fans.

Then I cut it out with a jigsaw and filed down the edges to a nice fit. As you see here, the left fan will be blowing out hot air underneath the motherboard while the right fan will blow in cooler air into the case, through the radiator of the Corsair H75.

Next thing to do was to make a new front-plate, this time in aluminium instead of stainless steel as before. I started out by measuring out the shape of the front-panel on a sheet of 1.5mm thick aluminium.

Then I started cutting out the rough shape with a jigsaw, I always cut a few millimeters outside of the line and then file it down to get the perfect shape.

I will be using a 4x20 character LCD in the front which will be showing temperatures and media info as this will PC will be hooked up to my TV. A 16mm anti-vandal switch with white LEDs will also be installed in the front-panel, I had to make holes for these two components so I started measuring out the holes.

For the power-switch I used a drill, made a 5mm hole first and then went on to using a 16mm drill. Aluminium is softer compared to steel, so to drill out a big hole like 16mm you have to be very careful so that the plate does not warp, some cutting oil and low speed on the drill worked for me.

I used the same procedure for hole for the LCD, cutting it out with a jigsaw and then file the edges down to the perfect shape, takes time but you get a very nice result.

 

This is everything for this blog, next time I will start working on the backplate as well as sleeving the cables for the PSU, LCD and switches.

 

See you next time!
