Grab a stack of CMR drives from serverpartdeals and you'll be good.
That being said I've run enterprise drives, and consumer drives and for home use I've never noticed a marked difference between the two in performance.

You could use Node-Red for the front end to run a Python script to issue a remote service restart commands either with a native library or by leveraging PSService from SysInternals.
What's the coil voltage on your relay? Also is this a raw relay or one on a PCB with a diode, etc?
It sounds like your relay wiring might be a little messed up. Assuming you don't have the auto return model, according to documentation on the US Solid site:
How to wire this valve?
In direct current (DC) situations, the red wire is connected to the positive terminal, and the blue wire is connected to the negative terminal. The valve opens when the yellow wire is simultaneously connected to the positive terminal with the red wire, and the valve closes when the yellow wire is disconnected and the red wire is connected to the positive terminal alone. This means that the red and blue wires are always connected to the positive and negative poles, respectively, and the valve is controlled by parallel or disconnection of the third yellow wire with the red wire.
So for that you want Red to the Positive on your 12 volt PSU, blue to the ground, and then the yellow on the NC or NO connection on the relay, with the common on the relay tied to +12VDC.
Check out Node-Red if you want an easy way to program on the PI and interact with the GPIO.
100% doable with Home assistant
doorbell (similar to ring with camera
Check out the Reolink PoE doorbell cam, works great with HA
connected speakers throughout the home
Check out Volumio, works great with HA
and connected lights preferably with a sleep mode (timer that slowly dims the lights), all connected to the same app preferably
Most Wifi/Zwave lights/switches are supported in HA, including Hue and Caseta.
Raspberry Pi for Home Assistant. And a second hand engineering workstation off eBay for everything else. Take a look at the Lenovo P700.
