Would i be able to switch cases with a dell computer?

I bought a dell 9000 and im not impressed with the cooling. So i am thinking of buying Cosmos S case. But here is the problem and question, First is does dell use some different kind of front panel connectors because i dont see it on the motherboard. And the other one is there are no fan headers on my motherboard so how would i get extra fans to run in my computer.Would i be able to switch cases with a dell computer?
Is the CPU running too hot??? If so, this may be a warranty issue, call DELL FIRST.





If it is, and it's out of warranty, just upgrade the CPU fan. There's no need to replace the whole case.





Then, wait and see if it still runs hot, and if so, there are adapters to connect extra fans to a free Molex connector (at The Source / Radio Shack, for example).
