Need 2 more servers... Suggestions?

[TechieSooner]

I need two servers to run 100 users each on.
My current server isn't going to cut it for long.

One will run Exchange, and Blackberry Enterprise Server.
The other will be my Application server. I run a couple hefty applications on this one (probably at any time, to plan on 15 people running these). Terminal Services.

Current server will stay the DC, just file file storage, Active Directory, Anti-Virus, that sort of thing.

What do you suggest?
No preference on rack-mountable or not.

I'm not building my own, just don't want to be my own support... I'd rather have a 4 hour response warranty.

first server

quad min , as much ram as you can afford.. I/O doesnt have to be super but exchange does like a separate array for each item as i recall from Exchange 2000.

exchange files
log files
and a separe install drive.


2nd one serving out apps i would think would need some fast harddrive sub system and cpu power.
