This is a near-religious question, you do realize. :)

When clients have healthy budgets, I go for HP Proliant ML360/365 G7
(Intel/AMD). Any tier 1 vendor will over-charge you for storage, I've
found. Your requirements are modest and your budget is healthy, so you
should be fine.

Regardless of who you go with, be sure to get a good RAID controller
with either BBWC or FBWC (battery or flash backed write cache). Stick as
much cache onto the controllers as you can afford (1GB at least).

If you expect your disk I/O to exceed a sustainable 125 GB/sec, you will
want to look at 10 Gbit NICs for DRBD. Regardless, I've found it a
worthy investment to have dedicated, bonded (mode=1 Active/Passive)
interfaces dedicated to DRBD and a separate network connection for other
