Check for prices on a Ryzen 5600X and a B550 motherboard. You should be able to find both for about the same price as the intel parts in your list.
It says on pc part picker that there is a compatibility issue when putting a b550 in
With the ryzen 5600x
It's not an issue. The motherboard may have a Ryzen 5000X ready sticker on it. If it doesn't, you need an USB to update the BIOS.
Huh? This is my 1st pc build and i did jot understand anything about the Bios
The b550 boards were produced prior to 5000x series from amd, so the bios version that's on the board may not support the 5600. However, most boards have been updated with the new bios so you don't have to. But just in case, if you get a board that has the bios backflash, you'll be able to update the bios yourself if needed without having a cpu inserted.
Also what b550 Motherboard should i pick
It wouldn't matter much. The MSI b550 tomahawk or a Asus B550. Mostly make sure it has the ports you need.
How do i know what ports i need?
Regarding that, what's your part list?
As other people said, Ryzen 5 5600X with a B550 board is a great option. 4000MHz RAM is a bit overkill, the extra performance over 3600MHz is minimal, you could save a few dollars on that
I swapped to G.Skill Trident Z RGB 16 GB (2 x 8 GB) DDR4-3600 CL18 Memory
Also is liquid cooling hard to install / do this is my 1st pc build ever
