I would like to throw some caution in the wind about this. Before getting anything be very to sure to check

• how power hungry the platform is (even on idle)
• check the drive types used by a mobo always
• make sure you get something of which memory is normal as expected

Aside from that, by all means always try to make a small home lab first (a laptop with a broken monitor can work for this, even a phone really) and then commit to something bigger once use cases are found
