At ~£54.80/$76.71 including shipping to the UK. If you are really unluckly you might get charged with VAT (@17.5%) by UK customs on top, making it a possible ~£64.38/$90.13. Which would make it only slightly cheaper than the MC462, which can be bought in the UK now for around ~£68/$95 with the Sanyo Denki fan.
I did suggest to Overclock.co.uk to stock the Glaciator and they contacted MTS back in June, but as yet no reply. It seems International orders and International resellers aren't a priority for MTS.
Hmm, Pete over at Overclock Ltd is saying they are sorting out delivery options and should get the Glaciator in stock within 7-10days if all goes well. Unless any of the other stores in the UK are keeping quiet, Overclock.co.uk will be the only ones selling the Glaciator in the UK, for a while at least. No idea on price though.
