My advice would be NOT to get a 65 - get a 75. The 65 is 36" long (with a center brace) and the 75 is 48". The majority of mixed (MH & PC or T-5) hoods for 65 gallon tanks have one MH in the center right over the brace.
If you're set on the 36" length, get a 58 - it's almost the same size but no center brace.
