MSI kept its word with me when it came the warranty. I had done some upgrades to a GT60 laptop that I bought all the way back in 2013. I had already added RAM (put a total of 24GB), upgraded the Wifi, and added an SSD.
When I was upgrading the WiFi for the 2nd time, the screen went all wonky and the system wouldn't boot. I filed a warranty claim with MSI and they replaced the motherboard, CPU (socketed, not soldered), and replaced cabling, along with some dust clean up.
They won't warranty any parts you replace, as should be expected, but the warranty was honored on everything else.
The GT60 was a fine machine. I still have it and it works well. I've also done some further upgrades, including replacing the CPU and graphics card. It originally came with a 3630QM and I replaced it with a 3920XM. The video card uses an MXM slot, so I upgraded the 670M it shipped with to a 970M. I had to grind a little of the heatsink with a dremel tool (10 second job) and use a modded BIOS, but it runs like a champ. Before the modded BIOS was available, you had to use a modified driver. There was a "how to" on another website's forum that has detailed instructions on how to do it.
Thing still runs like a champ, 7 years later. Only downside I found was that it didn't get along with Windows 10 as MSI never made drivers for it. So I have Win 8.1 on it with a Windows 7 skin. Still works great.
MSI told me at the time that the warranty sticker was on there to discourage people that didn't know what they were doing from opening up the system and tinkering, but otherwise the warranty held. That was true in my experience, and I'd assume it to be true in the future.
Think about it - especially when MSI makes a lot of products specifically for gamers and people who love to tweak their systems.
