ANTEC 900 Top Removal + 200mm Fan Replacement Guide
Top Removal
1. Obviously turn off ALL components attached to the case (I.E. PSU, and such)
2. Proceed to take side panels off (One is only needed but case is easier to handle)
3. Proceed to unscrew 2 screws (Marked in Yellow in photo) located at the center of the Upper Case (usually visible, but hard to find at first look)
4. Then, push all 4 retaining clips through, NOT alot of pressure is needed on these clips (AKA don't break them)
5. Give alittle tug for upper retaining clips to release (*BE CAREFUL due to CABLES are still attached to internal components and case)
6. Do a 90 degree rotation of upper panel so the fan is accessible.
Replacement of 200mm fan (BIG BOY 200)
1. Remove 3 screws that hold fan in place (Marked by green in photo)
2. Remove 200mm Big Boy fan
3. Proceed to place new fan in.
Reverse order to proceed to "normal" structure.
If this helps anyone, please post!

Thanks for posting this! Info on how to open the top of the Antec 900 case helped a lot. I have a huge XIGMATEK HDT-S1283 heat sync with a 120mm fan and it was a pain to get it all mounted in the case without taking off the top of the case. Thanks!
Regarding Step 3 of the top removal, I can't see any screws, only solid plastic. The only screws I see are 2 tiny ones accessed from inside the case, and I don't see how these could be the ones you refer to. Is it possible that Antec changed this?
I believe the "B" was a change in how the slots lined up in the back, I recall reading about it when I bought mine after seeing some comments. It's been a long while but I think it had something to do with how the PCI-e lined up but mine was a "B", so I've had no issues until now. The 200mm replacement lead me here, it's about dead...
So do you have to take off the front first as well? And are the screws under the top? Because I don't see any either. There needs to be a little more detail. My top fan stopped working and I'm going to replace it.
Thanx for the post,it really helped me,i was struggelin' cause i thought i did not have to remove the 2 screws in the middle,so i had stuck a pencil in each one of the corners and was cursin'cause the top still would'nt let go,back to the computer,googled this siet and 1 minute later tataaa!
yes, i have had my pc with the antec 900 now for over a year or so.. and the big boy fan went out. i thought i turned it off becuase of all the dust and whatnot.. but turns out it was broken stupid me. my one ? is where can i get the fan at. .i bought my rig at frys.. thanks
