This isn't that uncommon. I know Tyan makes some 4way systems that run off coldwatt PSUs I think.... they're basically just 12V PSU and 5VSB... mobo does all further conversions. Really 12V and 5V is all modern motherboard designs really need, well and 5VSB. Getting rid of 3.3 would be trivial. So l...

ZALMAN ZM850-HP 850W -- Best PSU to buy?

Ignore the capacity being a big number.. http://www.newegg.com/Product/Product.aspx?Item=N82E16817379007 As long as this is similar to 1000W version, which it looks to be, at $159 its hard to pass up IMO.

Googles real world data on 100s of thousands of drives show higher temps do not cause failures, lower temps actually increase failure rate.

40-45C had lowest AFR
50C and 30C had equal failure rates.
25C had over double the AFR of 45C

Some of the 40mm fans in 1U racks have two counter rotating blades... whats really neat tho is the '2nd' one has a different blade shape. The fans are insanely loud (12k rpm lol) BUT they do create crazy amounts of pressure. No application for silent computing but neat fan design.

Generally if you can get it to boot it'll work fine... many network devices need very little storage and hardly do any IO to wear out a device... CF cards have been being used in highend network devices for many many years without issue-- doubt you'll see any.
