AMD are phasing that platform out right now, but it's still available since there isn't a direct replacement at the same price yet.

From this info I spec’d out two builds and compared it with the Proliant Microserver: https://docs.google.com/spreadsheets/d/1MVxGsreiGKNXhfkMIheNFrH_GVllFfiH9RU5ws5l_aY/edit#gid=199471438 <https://docs.google.com/spreadsheets/d/1MVxGsreiGKNXhfkMIheNFrH_GVllFfiH9RU5ws5l_aY/edit#gid=199471438>
You’re right, the toughest part with low-end hardware is finding high quality and/or dual-port NICs, which is what seems to make the Proliant a pretty good deal. Most hardware in this range has Realteks, which might be ok, but I’m not convinced, so I added a dual port Intel PRO/1000 to each of my two builds, which then makes their price a bit higher than the Proliant.
One advantage to the external PRO/1000 is that it supports PCIe x4 whereas the BCM5720 that comes with the Proliant only supports PCIe x2, so there’s a bit of a difference here, which I may or may not notice. On the other hand, the BCM5720 supports hardware timestamping whereas the Intel does not.
I guess I should focus on the big picture here, either quad-core is important vs dual-core or it isn’t, and either I can do my testing with one box for both client and server or I need two. Neither I’m entirely sure about, so I might end up ordering something with the option to return so I can run some tests.
Thanks again for the tips...
