Home Hosted Dedicated server : Advise please
A friend of mine proposes to sell a few used server hardware to me to host our demo servers at home. With UPS and 1 static IP, at this moment, the System config is about 128 GB RAM, 1 TB, 2x Hexa-core [24 therads], and high-performance system each for about 425 Euros [converted]. Price is tempting for the HP Z800 workstation, with a 1-year my favorite provider's dedi auction server, I could buy 2 such hardware per year, 30% variance expected.
We have ISP who ready to provide a cheap monthly static ip with speed ranging from 0 to 200 mbps [upload/download], live in an apartment with generator backup, with small home UPS that can hold power for 15 minutes on the outage, we could run with 80% to 90% availability, which is OK. Power bill expected to add on 8 USD per month + Internet we already pay anyway.
I am not used to these setups, am I missing some big picture?
