That's one great thing about DS I was going to post but didn't before - they have US based in house tech support for their computers. It's nice to hear that they are comptenent, I'll remember that post Mbailey when this topic comes up again.
They remind me a lot of a friends former company, sort of a "custom" gaming PC builder too. Voodoo PC was the name of the company, it was based in my city (Calgary) but was famous worldwide during the PC gaming days from 1999 to mid 2006 when they were bought out. A lot of celebrities bought their PCs from Rahul the owner, including the now departed Robin Williams, who was a HUGE gamer, as were his kids back then. Voodoo always had the rear page add of all the big gaming magazines of the day like PC Gamer and PCXL. A big reason we have liquid cooling for PCs today was that Rahul innovated the idea with VoodooPC back over 15 years ago, making custom liquid chilling/cooling systems for their top end PCs.
Anyhow, Digital Storm builds a similar product, yet you can get a pretty decent base model which is competitive in price to other budget minded places if you select a non-flashy case and all that/etc.
