well undervolting your CPU/GPU isnt going to save you from crappy HDDS...

Call intel?

Intel cpus all have different voltages and pretty much use the minimum voltage that is needed to operate. You won't be able to undervolt much if at all. 

The money you would save undervolting is pretty small. Turn off your PC when you aren't using it, thats the most effective way. Why spend money on parts and then limit them?

If you are unlucky than you should just stop tinkering and leave it stock the way the smart engineers from Intel designed it. Also, you should be more specific about what hardware you have.

You could always get a Razer Tartarus or Orbweaver keypads and don't get distracted by the fact that they are "made for gaming" since you can really enjoy this in any context like I do with design apps. They are fully programmable with multiple keymap, unlimited macro and per-app settings.
The Orbweaver Chroma version also support per-key RGB lightning which is cool for macro identification. 

Something like this?

I'll start doing that when I finally get my rig and I don't have to use my mom's laptop

That depends on what he wants to do.  Like I said, #1 is making sure it has enough inputs, but besides that, a good eq (ie, as many controls as possible) on each channel is good to have, as well as the number of digital channels it can send to the computer.  For example, if it mixes all the inputs down to just stereo when sending it through USB, that's OK, but if you find one that will send each channel separately so that you can end up with a track for a mic, and a guitar, etc that makes editing in post possible and a breeze.  As for the best brands, the one a linked is quite good, but there are a number of nice ones - just check reviews and you'll see.

to start, know your size.  do you need like 4 inputs, or like 50+ (like the massive things you see in a studio)?

Hmmmm, seems interesting. What is your budget? Also, by all means I am not the best on the forums about giving audio advice. I just know the good vs bad brands. (my bro is a producer)
