Dell Optiplex 9020 vs HP Elitedesk 800 G1. Which one is better for hackintosh?

I can get both at similar price, optiplex is slightly more expensive (10%)

Optiplex 9020 is running i5 4570 + 8GB of ram.

Elitedesk 800 g1 is running i5 4670 + 4GB of ram.

They will get a Nvidia GTX 970. Also ram isn't important because I got some extra ddr3 sticks.

I'll be using this as my secondary PC. I know the performance will be very similar, so my #1 priority is hackintosh compatibility and future support. I never bought a pre-built before and my only hackintosh project are laptops so I barely have any idea.

Thanks!
