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?**

For the love of the flying spaghetti monster; don't ever pay retail.

We just did a large purchase from Dell for a bunch of servers, an EMC CX4 SAN, switches, load ballancers, etc. With full Microsoft licensing we paid easily 30-40% off the original quotes. It's all about having a good sales rep, and being able to negotiate when them and get them to work the partners for the best possible deals.
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.)
