IBM or HP servers that are asterisk compliant

I am looking at installing Asterisk on either a HP Server Model ML350T05 5410 or an IBM Server Model IBM X3550 QC E5420. Has any user had any experience installing Asterisk with either of these or similar servers? What issues (if any) were encountered?

Asterisk itself will work on just about any hardware. If you are usuing an analog or digital voice card it should run fine in any hardware as well. The most common issue is when the cards share IRQ’s with other hardware. You should try to put any voice cards on there owm IRQ to avoid any conflicts.
