I have recently upgraded to a i5 2500k build due to my old system starting to chug along at a speed that seemed to go backwards in time. Whilst putting the system in my old Antec 900 i could not believe the amount of dust, the cleaning of which added around 2 hours to my build. I was also a bit worried because the cable management is not good (non existant with my ability) and the Graphics card was a tight squeeze (old 8800gts).
Im looking in the next few months to upgrade the card to possibly a Crossfire or Sli setup but really think that I would struggle to get that in the case.
So what I need from my first post is some suggestion on a replacement which needs to fullfill the following criteria

Im looking in the next few months to upgrade the card to possibly a Crossfire or Sli setup but really think that I would struggle to get that in the case.
So what I need from my first post is some suggestion on a replacement which needs to fullfill the following criteria
- Cannot be much bigger in height or depth than the Antec
- Needs good dust filtering
- Needs good cable management
- Needs to comfortably hold 2 cards in a sli/crossfire (Possibly cards like the 580 )
- Cost less than £100
