I’m not one to really go nuts over most “clearance” sales, but I’ll make an exception here. Sun has put X4100 and X4200′s on Clearance! These all look to be non-M2 systems! Snatch them up while you can!
If your asking, “why would I want non-M2 X4n00′s?” the reason is that the X4100 M2 and X4200 M2 have 2 NVIDIA Gigabit Ethernet Ports and 2 Intel EtherPro (E1000g) Ports, versus the standard X4100/X4200′s that have 4 proper E1000g’s. See my rants on the subject here.
These systems offer a lot of value, especially at reduced prices. Snatch them up while you can!
