You have a company with a horrible track record for customer service and response. You have people on VPS accounts from dinix that not only never got their data back, but can't get a response from WHP, and still get bills from them. Knowing what you know about them, you are seriously considering sending them hardware that could cost thousands of dollars, trusting that they'll take care of and even return it when you ask for it? You're a much more trusting soul than I am, because given their track record, I wouldn't ask them to hold a stick of gum for me.
Funny, I e-mailed him a few weeks complaining about him spamming me and he apologized. Just yesterday, I received yet another e-mail from their sales. I would personally stay away from them, whether it be deciated or colocation or any kind of service they provide. They're following the footsteps of Aplus.net.
There are plenty of excellent providers around that you can choose from. I'm one of the ones that lost data (although I had back ups) from the Dinix/WHP debacle, and this is something that you don't want to find yourself involved with..
