Anyone every purchase / use hardware from <http://SiliconMechanics.com>?

Their prices seem to be unbeatable.

So I'm curious to know how reliable their servers are.

**Also, who do you recommend to buy the best bang for your buck on rack servers?**

I have a Silicon Mechanics rack mount that I bought used. It is a dual socket Opteron system with a 3ware raid controller and I have had no hardware problems with it. A friend bought some used on Ebay and those have worked without hardware issues. My former employer has a dozen Silicon Mechanics boxes that they use for Test and Production. The only problems those boxes every had were software issues with our own code.

If I were looking for new servers, I would put them high on the list of vendors to get quotes from.
I've used a variety of vendors over the years and I always come back to Dell. Their build quality is hard to beat. For important servers, I love the fact that I can call them up and say "it won't boot" and 90 minutes later a guy shows up with a box full of parts and begins swapping them out until it works.

Fried motherboard on a production mail server. Total downtime: 2 hours. (Yes, it should've been redundant. It wasn't.)
