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?**

Fyi; [SilliconMechanics](http://siliconmechanics.com) is just reselling branded [SuperMicro](http://supermicro.com) machines at a lower cost than direct with added support and sales. Still cheaper to buy from them than elsewhere -- but their equipment does come from a bigname whitebox manufacturer.
I bought 3 servers from them probably 3 years ago. 

2 servers had the (cheap plastic) rabbit ears break off almost immediately. One server was RMA'd. 

In terms of operations and not cheap plastic case addons, they've been reliable machines. I've heard their quality has improved from the models I bought.
