adding Rack Handles onto ATX Computer Tower or buy purpose-built rack PC case?

Hi All,

Just wondering if anyone has successfully added rack handles onto a PC tower case, and then fit the thing into a rack?

I have an unused new ATX PC case ready for a new build, but i seem to be moving towards a rack setup for my few pieces of equipment, and it would make sense to put the computer in there too.

But i'm not sure if the case would be strong enough to support itself, or if i need to just sell this case and get a purpose-built 3U PC rack case. 

All comments/insights welcome!
