Good for the OP that his HP is working fine.
I wanted to chime in on the notion that there have been "so many" issues with custom built DAWs.

We all know what I do for a living (and obviously I'm biased).
That said, a custom DAW is as good as the person building it.
The whole reason to go with a custom machine is that you have total control over what goes in... and how it's configured. If you make good choices, you wind up with a great DAW.
An experienced computer tech can choose individual components that are part-for-part superior to any pre-configured computer (Mac or PC).
I like Walmart as much as the next guy. Low prices are great...
First Act guitars work... but would you recommend them instead of Fender, Gibson, MusicMan, Rickenbacker, etc?
