I purchased the above case for a T5-76. They will custom make a case depending on size of keyboard and dimensions. I spoke to them by phone, then e-mailed the dimensions of the board.

Would I buy another? This does the the job it's light enough and is hard shelled. The downside I've always used Guardian cases and miss the top pocket for storage of cables and other small items. If I were to buy another case for the T5-76 I'd shop around a little more. I purchased from this company based on some comments from another member but I was a little disappointed with it. Nevertheless it does offer plenty of protection.
