Bought the Lian- Li 011 Case and need a new Heatsink

So as the title suggests I bought myself a new case after putting my trusty heat conducted h510 to rest. But in my infinite wisdom I assumed the clearing would of been larger than what I already had. My current Noctua Heatsink is 40mm too tall for me to put the glass panel back on my new case so I've had to leave it off for now while I search for a replacement but I see a lot if different coolers at various prices. I'm either going to go for a All in one water cooler, or a custom loop. My Budget is around £300-£400 and I'm more than happy to sacrifice looks for performance

TLDR: I bought a new case and need help to pick a new hestsink. Either All in One or custom loop
