Hi, I am building a gaming PC. I found a different Prebuilt PC on the website I am buying my parts from. I want to know which one of these 2 are better.

or

My PC - $3250.21 (Postage and GST and Parcel Protection) -

CoolerMaster Cosmos SE Full Tower Case with Window $179.00
LG GH24NSB0 24x SATA DVD-RW Drive OEM $25.00
Corsair AX860i Platinum Power Supply $325.00
Intel Core i7 4770K $399.00

I already bought my custom build, but I just want to know which is better. The main purpose is gaming and video rendering @ 1080p or even 4K.

Thank you.

Yours is a better case, power supply and motherboard IMHO. Other than that, they are about equal in terms of performance.
