Hi Watto420 :thumbsup:

I'm going to tell you to save your money.
The unit in the link you provided is worth maybe $150 for all the parts.

And I really don't think an 16 to 18inch tall computer case is a good place to
grow anything.

I think you would money ahead to go to a secondhand store and buy an old
cabinet or enclosed end table and build your own.

There is a lot of information to be found here on building your own and I believe you will be happier, and surely money ahead.

Just My Opinion

:hippy:
