Ordered a 1U from them. Going on a month now with no delivery date yet and no indications there would be a problem until after we ordered. Not a big deal for us, we can wait and ordered it because it was cheap, but consider yourselves warned.
My data-point, as best I can recall:
- ordered a serval laptop
- long delays with minimal communication
- laptop arrived and motherboard died within a few days
After sending it back for repairs and haggling over the warrantee (DHL damaged the case, so they didn't want to pay for the motherboard initially), I got the thing replaced and it ran smoothly for many years.
EDIT: to be clear, I was ultimately happy with the device itself -- it finally died in 2013. It's rather the shipping/service/etc that was disappointing, though I've seen much worse.
