Cooler Master CM690 mod project (56k warning)

Postby slngsht » Mon May 19, 2008 8:17 pm

So I bought a Cooler Master CM690 on the suggestion of a friend who said that it was a large case with a well designed layout and a bottom mounted power supply, which you usually find on more expensive cases. I spent $79 on it.

Stock, it looks like this:


Image



I got the case, and was looking over it and decided I wanted to spruce it up a bit.


My case stock looked like the following picture:


Image


First step, completely disassemble the case.


Image
Image
Image


Some of those pictures were taken after I stripped the outside of the case of the feet and all plastic and screws so only the metal inside shell was present. I also had to remove the tooless motherboard slots and 5.25" bay tooless hardware.

My first idea after it was disassembled, : Cut out the mesh holes that the fans mount on to minimize dust buildup by the fans. I didn't need all the fan bays because that would just simply be overkill and I don't want the case to act as a quasi-air cleaner, so that's why I only cut out one. I chose that one because the cpu heatsink would completely cover up the rear fan if I were to mount one there and would basically be useless and unnecessary.

Image
Image
Image

Next step: Paint the dull gray metal inside flat black.

Image
Image
Image
Image
Image
Image


I forgot to get a final picture of when the paint was dry. I used Krylon Flat black to accomplish that.

Next, I was looking at the plastic outside of the case with the mesh grill and brainstormed on that. The plastic is black and there is black mesh grill that goes all over the outside of the case. I figured that it didn't show off the mesh very well, so I decided I wanted to make it stand out more. Since I decided to go with the PC Power and Cooling 750W power supply, it was painted red. So I decided I should make the case's theme the crossfire red color, which is Candy Apple red color. Luckily, this shade of red came in a spraypaint, and so I proceeded.

I had to take off the mesh. This was the most difficult part of the mod because the mesh was held on by tabs that stuck down through slots and wrapped around the plastic holding it on. There were about 18 of these and it was tedious to bend them up and keep them straight so that they could go back in the slots later after it was painted.

Image

This is what it looked like after the mesh was removed.

Image
Image

To protect the rest of the stuff from overspray, i had to put masking tape all over what I didn't want to get painted.

Image
Image
Image
Image

Time to paint! I got really into this and forgot to take a lot of pictures, but you get the idea here.

Image
Image


After it was dry, it was time to replace the black mesh over the red paint and remove the masking tape.

Image
Image
Image
Image


As you can see, it turned out very well. At angles, the red disappears and all you can see is the black mesh, but as you move closer, the contrast of red and black fades in. It's really a cool effect that I wasn't expecting. It looks nicer in person because of the 3D effect of using both eyes. A camera cannot replicate the effect because it's only 2D.

putting the case back together was a chore to say the least. I was so excited to do the mod that when I disassembled the case, I put stuff in places and wasn't very organized about it. I spent most of the time trying to find the stuff I took apart. If you ever do a case mod, be more organized than I was. I eventually found all the parts, so it turned out okay.

But first, I wanted to do some more modding, but this time, not on the case. This time I modded the cpu heatsink and cpu.

I lapped them.

Lapping is basically polishing to the point of a mirror shine to maximize heat transfer from the cpu to the heatsink.

The processor and heatsink surfaces originally looked like this, and sorry about the picture quality, it was a cruddy camera i was using:

Image
Image

After lapping them, they looked like this:

Image
Image

Next, to keep with the red theme, I modded the heatsink, which is a Tuniq Tower 120.

Originally, they look like this:

Image
Image

I removed the stock black boring fan that came with the heatsink and replaced it with a blue LED fan that came out of the front of the case. I wasn't very impressed with the blue protruding from the front of the case anyways and just wanted it to appear black and red, so I put the tuniq fan in the front of the case since it wasn't lighted.

Image
Image
Image


Painted, and reassembly:

Image
Image

The blue LED's on the fan illuminate the motherboard without showing too much light through the grilles of the heatsink, which is a cool effect on the motherboard.

After complete assembly, it looked like this. it is not the final look that I'm going for. I want to post more pics after I get my new motherboard, and after I get a new video card or two. I also added a fan controller to the front of the case and mounted a floppy drive on the inside of the case as well, but I dont' have pics of that yet.

It's still a work in progress.

Image
Image
Image



To this day, the case isn't fully completed. I still want to install a window on the side which will take up as much of the side panel as I can do.

A few weeks later, I did a window mod.


This is the sheet of clear acrylic I got a hold of. No, the rest isn't for sale. LOL I used to work at a sign company and they had this laying around unused for a while, so I grabbed it up. I gotta return it now that I have what I needed off of it.

Measuring where I needed to cut with the dremel. the thing got too hot to handle and started smelling funny, so I took a break and made myself a ham and cheese sammich

yeah I did. it was my first case mod ever. I learned a lot from it. The paint on the inside of the case will chip off really bad. So easy, that if i run my fingernail over it it will flake off. Next time I'll use some automotive paint/primer to do it. Krylon just won't cut it with this kind of metal. Also, I ended up scratcing the cr@p out of my side panel with my jigsaw, so more painters tape next time. Also, I ended up turning the PSU upside down and did much better wire management through the back panel. It looks better now, but I don't want to take pics till I'm able to get the flaked paint fixed and a new mobo in it.

Thats a really nice mod you have there, thanks for sharing.

I did review this case not to long ago, I didn't cover paint as one of the modding options but I must say I like what you've done.

Once I get my new mobo and fix the paint, i'll take more pics of it and show some methods of wire management. That will be a while though.

That looks like a very cool affect with the red and black with the mesh.

The one thing I have learned over the years of painting is always use a primer before you paint with your desired paint. Even on plastics, I have had it flake off easier without the primer than with.

Also, didn't mix your types of paint.... aka if you use some water base primer, but a krylon for the top coat you will sometimes end up with undesired affects. And the nicer the project I will even sometimes buy all the same brand/type just to make sure I will have no problems.

Good advice. I'll do that next time. I had a lot of fun doing this case, hopefully soon, i'll find the gumption to do another one and do it right that time.

I like what you've done (except with the cable management, but seen as though you've had another go, but haven't taken pics, I'll let you off :P)

If you've got the time and patience, you should grab a file and round off the tabs (that are attached to the perspex) on the side panel. It'll help disguise the fact that they aren't 90 degree corners :wink:

But it's turned out really nice for a first time paint. I've always fancied the idea of painting the inside of my case black, but am worried I will screw it up, so it just gets left alone!

First off that is a great job. I love the red and black. You gotta clean up that paint on the door. It might just be the flash, but I can see a big scratch on it. I have worked a few times with this case. All I can say is for the price it is the Sh!@. You have done just one amazing job there. I can never work with spray paint all that well. You have done an excellent job with it. I'm like a pron star with paint. I shot it everywhere, and very uneven at that.

lol thanks. and yeah, it does have a nasty scratch right there. As for the wiring, I have since done a better job of tucking it all in the back of the case, so there's no excess hanging out in the front. It will be another month till I get the motherboard I want in it. When I do, i'll re-do the paint job inside the case and post some final pics. right now, the whole project is on hold.

:lol: i love that metaphor. I have olearnt alot looking at this case maily to undercoat, use car paint and put on a a finish weather it be mat or shine just to stop that damn pealing and scratching. I also would never be able to live witch the side pannle but thats just me im to much of a perfectionist.

All in all a very well modded case ( brilliant idea painting the insides black and i love the contrast bettween red and the black mesh it just clams the red down and ties it in perfectly i feal ) and i feel you will only get better in the future.
