My canvas for this project is the Cooler Master HAF 922

Image

Image
I'm using paper to make a template for 2x 120mm front intake plate.

Image
Tracking template onto 1/8" thick aluminum sheet.

Image
I used a Jigsaw with 18 TPI metal cutting blade to cut the design. I will refine and finish the cuts with a hand file later.

Image
The 1/8" thick aluminum won't fit in my bending brake, so I used my bench vise to bend the aluminum.

I'm using a Mouse sander with medium Grit sandpaper to remove all of the blemishes and scratching in the surface of the aluminum

Image

Aluminum plate surface is finished. Next step is fastening it on with pop rivets, more on this soon!
Image

Image

Image

I've attached the new bezel plate on with pop rivets.

In order to use the Knock-out punch, you need to drill a 2" pilot hole.

Greenlee Knock out Punches
Greenlee part # 730EBB-120 Last time I inquired, they were around $450 in the states + Large 3/4" socket wrench, and 2" socket. I wouldn't use anything less than 19" long socket wrench. Estimated purchase price of $550 new.

Unfortunately Cooler Master doesn't offer a window option for the 922, but this doesn't phase me. I chose to install a transparent red window based on the feedback I received from the CM Storm I modified. Just so you're aware, the Red acrylic is dark and I have not installed a window in the 932 HAF yet.

Here are the steps involved for the 922

Materials & Supplies:

http://www.mnpctech.com/UChannel.html

http://www.mnpctech.com/acrylic_colored_sheets_casemod_windows1.html

Image

Tools:
Ruler, Pen, Painters or Masking Tape (I prefer 3M Scotch 233+ Green Tape) , Rotary Tool, Jigsaw with 18 TPI or higher metal cutting blade, Hand File. Not pictured is Safety Glasses, Empty Box and X-acto Knife (or Razer blade)

Image

The HAF 922 side panel is similar to the CM Storm Scout.
Image

Perforated portion of the stock panel will hold 1x 200mm cooling fan or 2x 120mm.

Image

Start off by masking off the raised portion of the left side access panel with masking tape. I prefer to use 3M Scotch 233+ Green Tape. It leaves no sticky residue.

Image
Window location with space measurements.

Image

Use any roll of tape to make rounded corner. Round corners allow you to use the http://www.mnpctech.com/UChannel.html
U-channel window molding.

Image

Image

Before using the Jigsaw to cut the window, you need to make an incision cut with a Rotary tool with http://www.mnpctech.com/DremelDisc.html
Dremel 1.5" cutting wheel attachment.

Image

Image

Using Jigsaw with 18 TPI (or higher) metal cutting blade to cut the window opening. Notice I'm cutting on top of a box placed upon a stool.. This method allows you to turn the panel 360 degrees. It also collects the debris.

Image

Image

Using hand file to level and remove any jagged edges cause by the Jigsaw.

Image

I've measured 9-3/4" length section from a 24" x 12" acrylic sheet. The window should measure 9-3/4" x 12"

I have to ask, just for my own curiosity, and you would be the guy to know.........why do cases have to have windows now? I understand the popularity, way back in the day if you did an intesive mod, you couldn't buy cases that had pre-modded windows. There were some awesome designs back then, more art than "look at my guts!" Nowadays, just about every case you can buy has a window. Just curious as to why modders still do it, is all.

It's fun to look inside at the hardware :D

I dissected the chassis for paint. The top panel with the power switch and I/O is fastened on with plastic tabs, located beneath the top panel. Very easy to remove!

Image

The case chassis, just before removing the rear i/o slot covers, noise dampening felt strips for PSU and case feet.

Better open up the rear exhaust for improved airflow as well before the chassis gets painted.

Lets turn things upside down on the HAF.

Image
The bottom of the HAF gets modified with this 140mm billet grill.

Image
The slotted insert is removable, which makes tracing the inside easy.

Screen material I cannibalized from another case filters out the dirt and dust.

I applied the base coat on the HAF 922 chassis last night, this is Rustoleum's Grey self etching primer. It reminded me of Military Grey.. I love the color.
