Hydro X build on components from your signature. - fans and you are near your planned budget.

Total width of graphics card and the Hydro X water block is 153mm, it will fit in the Lian Li O11D. Width of the water block itself is 140.25mm

ASUS 2080 Ti Strix with Hydro X Series XG7 RGB 20-SERIES GPU Water Block (2080 Ti Strix) will work in the standard Lian Li O11D in normal orientation. Total height of the graphics card with GPU water block installed is 153mm.

Hi! Based on the product images, this one has a custom PCB layout. A typical 2080 block built for reference style PCB graphics cards definitely won't work with 2070 SUPER Ventus.

According to the GPU water block compatibility tool from Corsair, there is a match. I've used the '2060 super founders' to find the model from your link.

I would not recommend to pursue with trying to reuse the radiator from the Corsair H150i Pro with a Hydro X custom cooling build. It's aluminum based radiator and doesn't have the G1/4'' threading needed for typical custom cooling fittings. 280mm radiator offers plenty of surface area but it will depend on which CPU and/or GPU you are trying to cool. For a beginner I would warmly recommend to try the Hydro X Configurator.

Not a lot of performance reviews available but I've found these two.

Hi! The XS variant definitely doesn't have a reference PCB design. It's quite unique PCB so there are very small odds that there is/will be a compatible full cover GPU water block that would fit the XS Ventus. Non-XS variant has a compatible full cover GPU water block. The Hydro X Series XG7 RGB 20-SERIES GPU Water Block (2080 FE Rev.B)

Hi! On the product page of the AORUS GeForce RTX™ 2080 Ti XTREME WATERFORCE WB 11G there is a mention it's a copper base plate. It also uses standard fitting type G1/4". It's OK to use this water block model with Corsair Hydro X loop. Which particular make and model of the power supply do you have? With good models, 850W is plenty for your planned water cooling loop.

Hi! I've got some good news. Hydro X Series XG7 RGB 10-SERIES GPU Water Block (1080 Ti FE) is compatible with the Zotac Gtx 1080 Ti Blower Edition Rev.B. Attached are the images of PCBA, installed GPU water block and backplate.

Hi, since you are considering the RGB version, you may want to check the new Hydro X Series by Corsair. Reviews should be up by the end of this week.
