LoL on the topic ...
I was in doubt a bit too, but even with freight / VAT this came to an amount i had payed in EU, too.
Will do a mayor upgrade on the colo-rack in autumn, only willing to do any changes once a year as it's quite distant and not really fun working on a running cluster.
Going from 3 nodes to 5 to have some higher-freq CPU for some Workload and make a foundation for going CEPH somewhen. Also changing IB/10G infrastructure on this visit.
Currently have 1x 847 with SAS3 Expander, x9dri-ln4f+, LSI 3000 and Dual 2670 and 2x 826 with x9dri-f, SAS2 Expander, LSI 9207 and Single 2670
Will add 2x x10srl-f, 1620v3, uncertain HBA atm, and most certainly shuffle the boards from the current 826 to those chassis and putting these 2 boards to the present 826, eventually to an A-Backplane and use some SATA from the X10 in addition to the LSI. Also thought about upgrading to 2x 846 for the x9dri and putting the x10 in the 826.
Still not sure how it will exactly look in the end, initially planned the 2 new X10 Nodes for 825 i have, ironically wired them monday for burn-in
