Small Tower Server Recommendations

[topshot]

Hi, I'm after a mini tower server to run Hyper V 2012 with 4 or 5 VMs as a home lab (DC, SCCM, SQL etc)

Budget is around £450-£500 excluding extra storage/memory. I have looked at Lenovo TS140, Fujitsu TX140 and Dell T20 but cant decide which one to go for so any advice or feedback on these systems or any others would be great.

I haven't ruled out building one but think my budget may be too small?

Thanks for the replies, I did look at the old Gen servers but not all of them are compatible with 2012R2?

I've got a pair of Lenovo TS140's. Great performance for the price, 32GB, and you barely know they're on. Lenovo are dong a £50 cashback per server to. I paid £460 each.

Yes I have read reviews about them being quiet. Fujitsu seem to be doing £50 cash back too and their server is slightly better spec but not sure on noise/power consumption
