I don't know how many of you are IBM server authorized, but IBM is running a promo on their x306 model 88362SU. If you are looking for 1 1U server that works well with Sangoma (and probably digium) we have tested and have two of these series in a Master/Slave situation here and they've been performing great.
I know that some of the Dell's have been having problems with Digium cards, so I thought I would drop off an alternative. These should be available for around $500 without SATA drives just about anywhere, that's 1/2 the IBM web price. What is everyone else using for installs? Chad
