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.
We've (company I work for) used Silicon Mechanics for a while. Probably >20 servers from them, many of them with weird requirements, from low-end stuff (single-CPU, single-disk web servers) to multi-core, multi-CPU 16-disk DB servers, to weird stuff like telephony servers. We even got some Windows XP(!) servers from them fairly recently, no problems at all.

Almost all of it has worked perfectly with no problems. We've only ever had problems with three machines (one had a bad HDD backplane, found with intense testing on arrival, one had some RAM fail after the better part of a year, and the other was just Western Digital's lovely quality control), and their support (we just have the standard warranty) has been excellent.
