1. Buying online is SIGNIFICANTLY cheaper, we're talking about 50% markup at least for pre-built systems.
2. Buying parts separately means you have better warranty over all, each individual part will have it's own 1 year, 2 year, 3 year or even lifetime warranty that will be honored no matter what. Buying in-store will have a holistic manufacturing warranty and is less likely to honor anything more than a factory fault.
3. Individual parts also come with extra spare pieces like screws, SATA cables, molex connectors, adapters, hell most GFX cards come with a free game.
4. You gain priceless experience in building a PC. It's not as hard as people make it out to be, nor is it a dangerous process. As long as you build it on a flat hard surface and ground yourself on a solid bit of metal, nothing bad will happen.
5. If you want to upgrade a single component in the future or you want to do some hardware troubleshooting you are free to do so without voiding any warranty. Good look doing that on a pre-built system. If they find out you so much as disconnected a molex connector they'll void the warranty.
6. You have complete control over the quality of components you put in. With pre-built instore systems you have no control over the brand of HDD, the brand of SSD, the make of the Graphics card (sure you can pick AMD or nVidia, but will you get a cheaper Palit or Sparkle card or will you get a reliable EVGA?).
7. Most pre-built instore PC's use non-standard cases and layouts. These can be a nightmare for customization and horrendous for proper cooling. And they usually accumulate dust a lot faster than a standard cases.
8. The fucking PRICE. I've already said it but comparing prices alone makes it a no brainer. I could have built my computer almost 3 times over with the money required to buy an Alienware or HP equivalent (my PC was around $1500, the Alienware equivalent was $4100).
