Have to say my DIY is pretty poor (actually it's disgraceful - I failed Design & Tech GCSE ) so would prefer some off the shelf solution really
What does the hollowed out fan do ? Looking at the back of the case would the rad not just obscure a few PCI slots when mounted on the rear fan, or am I missing the point ?
Top of the case is out really as it sits under the desk in an IKEA holdy thing so not much clearance on top.
Did you keep any pics of your v1000 setup ?
