My case just arrived today! I could get a used Z77 mini itx board and use it for 6 month then wait for intel 10th gen and Ryzen 4000 series review before pull the trigger. Or just all in with intel i7 10700K. I only play game in 1080P 60Hz.
This computer is for office work and play 1080P games like world of tanks. I may make it as a hackintosh later. Intel cpu hackintosh is way easier to build. The only reasonable price Z490 MB I can find is ASRock Z490M-itx/ac, the other MBs are way too expensive.
My case should arrive next week. I give up lga 1155 build. The z77 used motherboard is very expensive. ($175) I decided to sell my mATX MB, 8 GB DDR3 memory, i5 2500K and 240 GB SSD on eBay AMD go for a newer platform. If I can get $110 from my used parts, it will cost me ( $160+ $70+ $150+ $115...
You would get extra noice from pump block constantly even while idle. 2070/2080’s TDW don’t need liquid cooler as long as you have good air flow.
Z490 motherboard are ready for release just waiting for CPU on May 27th. 10600KF 6/12 CT should be better than 9700K 8/8 CT and cheaper.
M1 case has great air cooler solution for both CPU and GPU. Noctua NH-U9S with extra fan and 2 AF 12-25 case fan at bottom setup as exhaust fan (remove GPU fan and shroud or replace it with arctic cool heat sink). Since you are going to use x600 CPU, it won’t produce much heat.
Everything will be based on your monitor resolution and refresh rate. Are you playing game with 1080P, 1440P or 4K? 60, 144 or 240 hz? After determine the GPU and CPU, you can pickup the right case based on thermal condition.
