Sometimes simple is not just enough. Specially when it's PC case. Here is my:

Step 1: Parts

Firs of all you need a PC case (Be sure to choose the right case for your PC components),
then you need wood and mediapan boards, glue for wood, Hot glue, Silicone, Glass or Plexiglas, Coolers, 12V Neon's for PC or car, oil paint or any glossy paint you find, LED's, wires, switches.
From the tools you need small saw, Hot glue gun, screws, air brush or brush, grinder, soldering iron, silicone pistol.

Step 2: Starting. . . TOP. . .

Step 1.:Firs take apart the case to the frame.
Step 2.:Than organize the things in your head where to put things, how to look like the case.
Step 3.:After the idea make the main part of the case (in my case it was the top).
I'm using 6mm mediapan for this. After I cut out the top whit paper tape secure the panels. that way I can cut out he other elements. When I finished with the parts, just glue together and left to dry 24h.

Part 4.:The original grid on the 12 cm cooler is nice but it's not fit in the picture! So I make one.
Firs find something you like (can be anything: butterfly, lighting, dragon etc...) print it in the right dimension then use indigo paper to copy on the wood plate.
the next step is to cut it out (after 2h of cutting I can't feel my arm!). Be aware if you don't leave connection part you wont be able to secure it! After cutting out use glue to secure it on the right place.

Step 3: The Main Body. . . Painting. . .

Usually The painting come at last but in this case the only things what waiting the paint is the top an the side of the PC case. After cutting out the side for the glass the main body is ready to paint.
I was using oil (mineral) paint because it has high gloss.
The inside was paint in white because the light's, but still some parts leave in matte black for the contrast.

Totally of 3 layers of paint the glossy is just great.

Step 4:

For better cooling there is 4 additionally coolers, one of them is 12cm fan with blue led what I put at the top! the others are 8x8cm fans.

Step 5:

The Front and the Top has its special and original ideas! The front is designed like an alien space ship(its function is power indicator), the top represent the heart of this project THE RYU (The DRAGON). There is a pair of dragon eye(HDD Light). To make them I'm using 1cm Plexiglas a cd marker hot glue and 2 3mm red led light, and a little acrylic silicone.

After cutting out he Plexiglas I secure it whit hot glue gun, above the eye I put the two led, and finally cower it with silicone. The silicone is paint able and not transparent so only the eye is visible. on the top of it I put the tinted Plexiglas. Its a cool effect in the night when the eyes turn up.

Step 6: Finish

After the final painting and assembly its done. The dragon is unleashed. Now you only need to put your pc parts in and turn on. Enjoy and I hope I give a good ideas to anyone who is too bored :)
