I was perticularly surprised that I could not find an actual post on this subject, so I made one. I just bought an Antec 900 and it needs cable management. At its current state I am not sure it will be able to fit higher end 8800s, but thankfully my first step is to buy a new PSU, PC P&C 750w silencer, that will hopefully help this problem. The thing is, I can not honestly see that helping. I have seen Antec 900s over the internet with some modding (cutting holes in the tray around the MOBO) that allow the cable to run around the back. Now, I am not expert on this subject, have never modded a case, and am not sure how running wires behind the tray works. To be honest I don't even know what tool to use for the mod. If anyone can put in suggestions, know articles that I may have missed, or have done this themselves, I would be thrilled to hear them. I have seen many people wondering the same, so I hope this post will be able to answer my questions and that of many others.
