Did it but just couldn't live with it. A couple of months ago I sold my 2010 MP 3.2 quad, 24GB, 5870. I just got tired of "old", whatever that means and was not having good luck with USB3. It was time to join a more modern USB3/TB world. I replaced the MP with with a 2012 mini 2.6 i7, 16GB and installed the 960GB M500 from the MP. For storage I bought an OWC Thunderbay 4 and put the MP's four HDDs in it. That was really an excellent hardware combination assuming I did not try to do too much heavy duty stuff all at the same time. I could recommend that setup to just about anyone and since I'll probably be selling the mini and Thunderbay I definitely will be recommending it. The problem was it wasn't a Mac Pro. I just bought a really clean, true 2012 in stock condition, i.e. 3.2 quad, 6GB, 5770. It definitely needs RAM, a CPU and a GPU but it feels great to have that stupidly huge hunk of aluminum back on my desk. The M500 went back into a MP and after entering a few passwords I'm back in the saddle. Sure the Geekbench 3 scores suck but it seems to work better than the mini. Compared to the Intel HD 4000 the AMD HD 5770 isn't too shabby either!
