Intro: How To: DIY Modded Computer Case

I was bored and decided to make a modded computer case. I did all of this by myself with the help from a few people for cutting the case and plexiglass. I hope this helps anyone wanting to mod their computer, but are a little skeptical. This is my first instructable so please comment and tell me how I did. I am only 15 so it may not look professional.

Needed materials:

Plexiglass - about 8 bucks (Local hardware store)
Screws $1.00 (Local hardware store)
Jigsaw (You can buy one online if you don't have one)
Drill (I had one)
Electrical Tape (pretty cheap at target)
Cold Cathodes, Lazer LEDs, and a LED Fan - with tax and shipping, $19.97 (
A computer hopefully and some hard work and time. :D

Thanks for checking it out and I hope you enjoy.

Step 1: Start Making the Window...

The First thing you need to do is measure the case and find a good size for the window. Then decide how big you want it to be, I chose 10 x 9 in. for my window. I went to my local Ace Hardware store and got a piece of plexiglass cut right there for me.

Step 2: Who Cut the Case???

Now you need to cut your case to fit your window. Make sure you outline your window with pencil and then take a ruler and go about 1/2 inch in the outline of your window so you have room to drill holes to attach it to the case. Then drill the holes and place screws in with nuts on the other side to keep it in place.

Step 3: Add Your Case Fan If You Have It.

I had a fan with a direct port to my cpu so I needed to add holes for that. If you look at the pictures, I drilled holes for ventilation, but decided to use mesh afterwards.

Step 4: Place Your Lights Into Your Case.

*Unplug you computer from all cords and power supply.*What to get: Cold Cathode (CCFL) Lights, LEDs, LED Fans, and what ever else you want. I bought these from they have very good prices, and fast delivery. To install just connect the plugins to the right spots on your motherboard.

Step 5: Testing! Check, Check, 1,2,3?

Okay now that you have all your lights hooked up, plug in the power supply and test this baby out!

Step 6: End Product.

Well there you have it! A wonderful Mod for under 30 bucks!

Happy modding, Please post any computer mods that came to mind from this in a comment!

    What are the specifications of that computer?


    What is the material made out of? A dremel should work with most cases. Note that my case is made out of steel. At least I think it is. It was pretty tough to cut.


    My best bet would be to buy a cheap case and replace it. Sorry if I'm not much help. I don't really know what else to say. Good luck.


    Reply 6 years ago on Introduction They have a load of cases, some with PSU's. A couple even have huge case fans and/or 11 bays! has a ton more. Starting at 32.99 many more cheap places. Just search around. So much info out there. google computer case. You'll find plenty of places. I got a nice case for 24 bux shipped just by digging around on the net.

    Dell motherboards and components are proprietary and you will have a tough time putting them in a different case.

    You may want to do what i did , I made a Big hole (1 inch) and with tin snips and a nibbler , cut all around were you want a windows , by this method I achieved to install a case fan into an HP pavillion PC , (belive , The metal of that case is really, REALLY though!)

    Yo may also want the nibbler , since cutting with tin snips leaves sharp edges
