The liquid spark is great it's a different amp to the magni it's a warmer amp to me it's a good pairing with the 6xx. Wither amp imo works great for the magni 3+..liquid spark has slightly less power. But the thing the liquid spark has over all the $100 amp is it's ability to do big boy bass that only more expensive amps can do. Measurements won't tell you the whole story. Dac wise ant of the $100 DACs would work with it .

Wow I did not think it was thermal paste at all, I feel dumb now but I think that may be the root of this problem since the problem gets worse as time goes on. As for the hard drive I recently gave her a new-ish hard drive because her old one was pretty much dead. I'll try the thermal paste solution when I see her next and since I already have a tube of decent paste it's a super easy solution. Thank you so much man, I would have never thought of replacing the paste and now that I think about it, it makes sense that the problem stems from the CPU overheating, it is a pre-built system after all. Again thanks for the help I'll keep you updated if I need anymore help. 

oops I was looking at a different card, the one you linked does not have a back plate so it will be fine.

It will affect the air flow because the fans on the the rad are static pressure and not air flow optimized. As for heat you will see more heat coming in the case unless you mount them as exhaust, but again air flow will be impacted.

No the software has nothing to do with it, It's probably dying so back up all of your files and see if Seagate will replace it since it should still be under warranty.

Not at all

I think it should be fine and I don't think a 270 is not super overkill but it is a little much
