found old servers.... are they any good for cpu mining???

[soulcancer]

ive been looking for a while and cant seem to find any info...
im fairly new at this, but Id like to give it a try..
I have a chance to pick up a couple of old servers for about 250$ total...

1. Dell Poweredge 2950 (2U Server)
 Dual (2x4) Quad core Intel E5410 Xeon processors (8 cores total)
 8GB DDR2 Ram (Max 64GB Ram)
 Dual 150GB SATA hard drives (system supports SAS or SATA drives)
and
2. Dell Poweredge R610 (1U Server)
Dual (2x4) Quad core Intel E5504 Xeon processors (8 cores total)
 8GB DDR3 Ram (Max 192GB)
 Dual 160GB SAS hard drives (system supports 2.5" SAS and 2.5" SATA drives)
 Dual Redundant Power supplies

my question, what kind of hash rate could I expect out of these two for say, monero or other cpu coin?
would it be worth it at the end of the day?
thanks in advance

8 cores seems good. Check the cache and go to the cheap miners build thread.
