Having own'd two of them, I have been quite happy with the performance and in the case that something did happen, Hypersonic was quick to fix the problem. On my GX-7, I had a noisy DVD drive shortly after receiving it. They painted a new drive and shipped it to me - no cost. Painted because my systems are painted metallic red. I was also plagued with the artifacting that a lot of the same model (Sager, etc) owners had and they replaced the motherboard and graphics card to fix that.
With my EX7, the only issue I had was my SATA drive died and they were on top of replacing that one also..... until the real, non-Hypersonic event happened. The mysterious send something through the mail and it vanishes deal. I didn't pay $5k to see a magic trick, but somebody thought I had.
That's right... my nice, awesome system, disappeared between the military post office in Germany and Hypersonic in NY (NY being the same state that the military post offices from Europe come into). I had insurance and I am making them either cough up the money or the system, but this sucks big time.
Strange thing is... I shipped 9 other boxes and all 9 of them made it here... except the system.
So if you run across a Biohazard EX7 out there, beat the crap out of the person who has it. Ok... that was mean - frustration showing.
That aside - if I have to buy another one - it will be Hypersonic for the third great system.
