I've put a lot in below, just to show you some chopices..you said about Lian Li case, so added the Lancool II mesh. As a differennt build put a 011 Dynamic mini with a 750W gold rated psu in there as a different build. Added the uni fans, bost SL and AL as they are on offer and can be daisychained, making cable management a lot easier..if went with the dynamic mini, top and bottom are 3x120mm, side fans 2x140. You could also go 011D dynamic for £135, then would be 3x3 120mm fans and take a standard ATX
Put both air and aio cooling..for aio, dynamic case best bang for buck is the arctic freezerII, it has the thicker rad. However, the X73 is reduced from £170 to £110, gives you a nice looking pump head and has some rgb is you like it...more than adequate for the cpu. For lancool, front can support 360mm rad or top 240/280
Asus have a promotion on at the mo(thanks to another forum member pointing out), the the Tuf gaming Z690 plus wifi has a £60 redemption if bought with a 12600k, £70 if you go 12700K. i also like the msi Tomahawk but it's £259.99, so Tuf better value.
Ram, Crucial non RGB 3600C16 fasted, then if going rgb the crucial is same but £20 more...sitting between the 2 is corsair vengeance rgb 3600C18...slightly looser timings so 1080p gaming you will loosed a few fps, but is slightly cheaper.
For storage and fast loading etc, the WD m.2 nvme's are all on offer..SN550 slowest to SN850 fastest(up there with the Sammy 980 Pro)..the mobo can take 4 pcie4 drives so future expansion s/b ok...with the price reductions I'd go SN850(pcie4) or SN750(pcie3)
I added a 850W gold psu on offer is going lancool case...you don't need that high for the 3060ti, but in a couple of years you want to upgrade your gpu, hopefully it will have enough grunt to power your next gpu..is also on offer at mo
All coolers at the mo will prob need a conversion bracket to fit to mobo to make compatible..I know artic will provide one free of charge with evidence of receipt..
