DUIT,
Sometimes it is easier to move the components OUT of the DELL CASE and put them in a MID-TOWER ATX case.
MORE ROOM and ya can replace parts easier, easier for AIR circulation, easier all around.
You can get you a nice case for under $65.00
Then, in the future if you want to upgrade to a newer motherboard/processor/MEMORY you simply change the motherboard and CPU and memory to go with your new motherboard.
This is what I would do if I was unhappy with the case.
Best to you,
micro...
