I have recently been looking at solution for hardware for a new home lab. The primary need was a lower power solution, with plenty of ram and the ability to run hyper-v.
The solution I have chosen is a small form factor from Intel called nuc5i5mybe. The hardware purchase list is as follows:
Crucial 16GB (2x 8GB) DDR3 1600 MT/s CL11 SODIMM 204 Pin 1.35V/1.5V Memory Module Kit CT2KIT102464BF160B ***NOTE THIS IS LOW VOLTAGE RAM compatible with the board***
M.2 Type 2280 500GB Fast Solid State Drive/SSD Crucial MX200
Total Cost: £613.18
This enables the running of several visualized guests, which so far I have two domain controllers, and one edge server allowing a site to site vpn to azure. This means my home lab can integrate seamlessly with the cloud offering from MS.
