I like the ThinkServer I mean I bought the cheapest one I could get for 600$… But if I had the space and electricity… I would probably like to have something like the DELL T-710 or DELL-T310 Series at home. (They are heavy) with a few 15K SAS Drives and Host Hyper-V on it.
You can find them now at 1200$
But the ThinkServer from Amazon, does the job for a Lab. I run 10-15 instances of Epicor on it, (all AppServers running) the only downside it has a low RAM Limit. Perhaps I can find one with dual CPU Slots and 128GB Ram would be ill!
