microcenter has generally higher pricing on parts other than their bundle parts but their open box or clearance stuff has pretty good discounts.

cooler example vids - https://www.youtube.com/watch?v=zTHCPsM5ECw for aio and https://www.youtube.com/watch?v=_Bv7Tn4zqRc for air. aio pump speed may be reduced to 50% without performance penalty on asetek v7 but should hold true for more recent pumps too. pcpp doesn't pick up a lot of modelvariation/multiplelistings on amazon, like the argb version of frozen warframe pro being cheaper than the non-argb version, and thermalright has multiple storefronts, and even a humongus lcd (toredo)is cheaper than the kraken, or a humongous screen that curves around the pump block is around the same price as the kraken

for 7800x3d bundle, the x870 mobo upgrade might be worth it, should you drop in a future zen6/7 cpu upgrade instead of going for the next platform, because the asus max gaming mobo has very poor vrms, 2x4 discrete mosfets, while the gigabyte gaming has 2x4 55A drmos, and 7800x3d doesn't draw more than about 85w max so the asus would be fine now if a bit warm but gotta watch out for it later. mobo spec sheet. the base boards in the 9850x3d /9800x3d bundles are good/bitbetterthangood in the vrm department respectively.

yeah used drives can be half the price of comparable new ones. gotta use the bios' secure erase feature on them(formatting means data still there just marked as empty not actually empty, secure erase writes all 0's) and some other risks like drive health low but should buy from the ones that supply the relevant s.m.a.r.t. data

psu tier list, and hwbusters.com

the corsair rgb ram currently provided in the bundles can either use samsung or micron/spectek ics, so manually tuning isn't great, though the advantage of doing so is mitigated by x3d, but theres still some gain to be had if you want to put in the time. buildzoid? r/overclocking ? this is mainly hynix refrences. suppose the least difficult thing to do for some gain would be to increase trefi(temperature dependant timing)?

see charts here in their latest review towards the bottom half for case relative performance, but no h6 flow in them... and case is heavily subjective. found comparison in techpowerup review charts, h6 only 7ish c worse in cpu with gpu about even, using 360mm aio and stock fans (with much hotter cpu)

since you're getting amd cpu there's this guide

if nvidia gpu install the drivers with nvcleanstall. recent large comparison between 'reasonably priced' upper crust amd/nvidia gpus. productivity charts. a 5070ti can be overclocked to 5080 levels. nv uv methodology

if going linux then don't get nvidia, troublesome and has a performance penalty of about 20% as of a few weeks ago i think. if windows then this is really good https://github.com/ChrisTitusTech/winutil
