Older Intel hardware is not recommended due to low/bad performance and new Platinum/Gold Intel Xeon systems have not been tested yet. (Chances are the new hardware is really good, but expensive)

New multi-core 64-bit ARM high-density HPC servers are hitting the market from Cray, Hewlett Packard, and others. Some of them have as many as 64 cores per CPU. This will be a market sector to keep an eye on for ARM's GFLOP::watt ratio advantage over Intel and AMD.

Sadly, these are likely to remain cost-prohibitive as hardware investments until a second-hand market develops.

Odroid XU4’s are popular. SBC systems, in general, are designed to be very power efficient, because of this they are pretty good a Verium mining.  The downside is you need a lot of them to amass a sizeable amount of hashes.  The up-front cost of SBC’s can be very high, but their power usage is very low.  Remember to take into account all the required extras to make SBC’s function. (SD cards, power cables/supplies, network cables, switches, cooling, mounting mechanism, etc…)

SBC’s are very good entry devices. Nearly any machine (Raspberry-, Banana-, Nano-Pi, Odroid,...) can run the wallet and miner software. For SBCs the mining software usually needs to be compiled for 1way using 128 MB per thread.
