[Sarathi123]

Hello there. i recently bought an hp 800 g1 tower. and i would like to fit a cpu liquid cooler , A new 850 watt psu (corsair maybe) and a dedicated gpu in it. and i dont know what type of(atx,ssf etc) power supply the case can fit and i also dont know if it will fit an 160x120x27 sized radiator in there! 

Edit. well i would also like to equip it with an 6600xt or maybe an rtx 3060 ti on it. and i would like to know if it fits inside the case!
Edit 2: here is the link for the psu. cpu liquid cooler and the gpu specs

@Sarathi123 -- I would be tempted to purchase an empty, full-sized, computer-case, add a high-wattage power-supply, remove the motherboard (with CPU and heat-sink) and disk-drive and CD/DVD from the newly-purchased computer, and then add-in the liquid-cooling system, the high-end GPU, and any other components that you are asking about.  Doing it this way means that everything will fit.

Given that you will keep using the HP motherboard, you should not have any problems "activating" Windows. It is the same motherboard, CPU, RAM, disk-drive, network adapter, and CD/DVD device, but fitting into a larger case.

Well The problem is that OEM hp mobo doesnt use an 24 pin connecter. it uses something called SH 6 power connect. and well. i dont want to blow my budget. i will be just upgrading the psu ram and a new liquid cooler. and buy the gpu later. i want to know how to use the 24 pin with the 6 pin connecter on the mobo. it sucks to see hp doesnt use an 24 pin standard connecter!

@Sarathi123 -- take a look at: COMeap 24 Pin to 6 Pin ATX PSU Power Adapter Cable for Dell Motherboard with 6 Pin Port 13.3-inch(34...

It has a 24-pin "female" (to connect with the usual 24-pin "male" cable on most power-supply units) and a 6-pin connector (for some DELL motherboards) that may also work with your HP motherboard.
