Allocate a box for use as salt master (probably syndic with multimaster eventually for redundancy) for codfw

I'd like 16GB ram, 16 cores if we have a spare laying around that meets those specs. This is lower powered than neodymium; my gut feel is that this will be enough as long as we're not running other things over there e.g. puppetmaster.
So we don't have any systems that are spare and have that core count without also having an insane amount of storage. We have the spares listed on the tab 'CODFW Spare Servers' on this google sheet.
So we've moved to less cores and higher clock speeds on the misc. specifications. So the spare systems I have available in codfw (that have dual cpu):
|Asset Tag||Hostname||Warranty Expiry||Rack||Model||CPU||CPU GHz||CPU Core Count||Memory||Disks|
|WMF5851||2016-01-13||A5||Dell PowerEdge R420||Intel® Xeon® Processor E5-2440||3.00||6||32GB||Dual 500GB|
|WMF5849||rbf2001||2016-01-13||A5||Dell PowerEdge R420||Intel® Xeon® Processor E5-2440||3.00||6||32GB||Dual 500GB|
|WMF6378||2018-12-07||A5||Dell PowerEdge R430||Intel® Xeon® Processor E5-2623 v3||3.00||4||32GB||Quad 4TB|
|WMF6380||2018-12-07||B5||Dell PowerEdge R430||Intel® Xeon® Processor E5-2623 v3||3.00||4||32GB||Quad 4TB|
|WMF6381||2018-12-07||C5||Dell PowerEdge R430||Intel® Xeon® Processor E5-2623 v3||3.00||4||32GB||Quad 4TB|
|WMF6382||2018-12-07||C5||Dell PowerEdge R430||Intel® Xeon® Processor E5-2623 v3||3.00||4||32GB||Quad 4TB|
|WMF6384||2018-12-07||D5||Dell PowerEdge R430||Intel® Xeon® Processor E5-2623 v3||3.00||4||32GB||Quad 4TB|
So I'd like to use either WMF5851 or WMF5849, since they have a total presenting cores (including hyperthreading similar to neodymium) of 12 actual and 24 ht-total cores. The use of the 4 * 4TB seems overkill for salt (but they are overkill no matter what, sata disks are cheap.) If we need this salt-master to eventually/poentially do other things in codfw, then one of the newer misc systems may be best.
@ArielGlenn: Please provide feedback? I'm assigning back to you for input. Once you have done so, this can likely get escalated to @mark for his approval and then back to me (@RobH) for implementation.
I'm assigning this to you for your approval of spare system allocation to a salt-master in codfw.
The system allocated is one of our older spares in codfw (chosen due to the low storage requirements of the salt-master) WMF5851.
The details of this system and the alternatives are listed in this tasks history.
Please review and approve/deny/question/clarify the allocation of WMF5851 and assign back to me.
In regards to it being out of warranty, that isn't enough reason to cease using it. In the instance of a salt-master, out of warranty is likely a non-issue. (We can spin up multiple masters and replace them when needed.) I don't make the final call on that though, Mark does.
