Re: from where can I buy the original Dell Optiplex 990 MT casing if you want to have the 990 logo exactly on the case then look for one on ebay or local market.  it will be easier to find a complete system than empty case. on the other hand, many Dell optiplex series 4 (790 to 9020) MT share same case w 990, such as 790, 7010/9010, 7020/9020.   only the logo is different.  
I bought Optiplex 990 DT about two years ago. I want to change the casing. I got to know that I can have Mid Tower Casing. My question is from where can I buy the original Dell Optiplex 990 MT casing. Is there any model no for the MT casing? if it is, what is it?     Note: I want the original Optiplex 990 mid tower casing.   Thanks in advance!
