I really don't understand the fascination with any particular cooler. Why would you want any particular cooler when teh first you can get cheaply that fits will be fine?
I've said this before and I'll say it again. The cooler is the easy bit. The cheap bit. This is not critical, the fluid and its level is, a cooler is a cooler is a cooler.
The money and the time to make it work will be in mounting it and the hoses.
£25 delivered should be all you need to pay. Raid your breakers; the hoses another £10enner; a few jubilee clips another £5iver. A Magnefine would be good, but no one seems to sell them in the UK.
All in, this generic cooler would do, as would any number raided from your breakers yard, a cooler is a cooler is a cooler.
