Thank you for the link.

What about an Intel Xeon E3 1220 v2 (4c/4t @ 3.1 GHz) - 16Go DDR3 ECC?

I would guess it will be ~20% slower than i7 2600.

I never knew Hetzner have marketplace/auction for HPC servers, that's very interesting.

I'll be a bit off-topic but hope the information shared here might be useful to everybody.

So, meteoadriatic, a couple of questions :)

1) Do you use Hetzner for real production use (running WRF on their servers)? If yes - are you happy with the service?
2) Does taking a server from the marketplace/auction have any disadvantages?

My story: I'm about to collocate my own servers to a data center in a month or so. However, given that: 1) they are slower than the ones I see on Hetzner marketplace 2) collocating them will be more expensive, I'm now reconsidering my initial strategy.

Thanks!

Regards,
Ivan

Well, that's just normal computers, far away from HPC, but again, better than nothing :)

Yes, extensively. Purchasing your own hardware on long run is better value, but if you can't afford or don't have infrastructure then this is great value. Hetzner's service is very good and reliable. I had only one issue with them when they immediatelly blocked one of web servers because client got pishing malware, no single warning in advance was issued. IMHO that was indeed very serious issue because they cut all traffic to whole server without single notice in advance. Apart from that, no problems yet with Hetzner.

No. Those are used computers, but I found no single problem.
