sweet setup

so ive decided to build my own sff build, the clearances for the graphics card and the case fans will be tight but should fit without any modifications . #AMD Ryzen 7 9800X3D #Asus Rog strix B850-I Gaming Wifi #Gskill Flare X5 DDR5-6000 32GB kit #Gigabyte 4080 SUPER GAMING OC 16G #Noctua NF P12 redux 1700 Casefans #Thermalright AM5 CPU Contact Frame V2 #Crucial T700 2TB Gen5 SSD #Cooler Master NR200P V2 Case #Cooler Master V SFX Gold 850W ATX 3.0 PSU #Cooler Master 280mm AIO

im at a crossroads, build my 1st pc and save 600 bucks plus i will use a 9800x3d in the build versus going with a new alienware pc with warranty and support ect. your thoughts please guys
