Well, I just spent all day and night researching and actually doing this. A lot of the reasons why people will transfer the X51 into a new case is that it doesn't support GPUs outside of what's supported 90% of the time. The problem is the 330W PSU just isn't enough for newer GPUs and I have personally experienced shutdowns on a GTX 970 and 1070 for a total of 2 years now. I spent dozens of hours troubleshooting from buying a new power supply brick to drivers and hardware. It's just not enough power and as much as I absolutely loved my X51-R2 it was time say goodbye. I spent $400 on a new GPU and 5 seconds into Wildlands or The Witcher and it shuts down. It was a gamble with the 970 as it would only shut down with a select few games. I got frustrated and one night tore the computer apart and transferred it all over. I also used the correct blower style cards and they were reference GPUs as to make sure they weren't overclocked and consuming too much power. Before I actually spend several hours writing the guide, would anyone be interested? There's currently no comprehensive guide online as I had to piece together info from dozens and dozens of forums and also use my own guess work. It's not an easy task but can be done on a $150 budget for people who still want to use their parts. Let me know what you guys think and I will provide support in this thread for as long as people want. Part List: Case: Raidmax Viper GX $70 Fans: Antec TriQuiet (x3) $7 ea. Cables: Generic SATAIII cables (x3) $3 ea. PSU: Corsair CX750M $80 Thermal Paste: Arctic Silver Paste Remover and Arctic Silver 5 Paste $20 Final Total: About $200 [UPDATE 4-21-18] I just wanted to add some info here for new people who are looking to do this. For one I don't have this tower or any original Alienware parts anymore as I've long upgraded past this, but I still provide support as I still love Alienware. Second, this setup is such as pain as the motherboard was built around the chassis of the X51 and isn't a standard motherboard. For one, there's no IO shield as it's built into the chassis of the X51 case. I had to put clear tape over the IO ports and cut out the ones I use as to reduce dust intake. Second, there are only two fan ports on this board and one is blocked by the GPU. The GPU was designed to be in the X51 cage and not directly plugged into the board. The fan port is literally right next to the PCI-E 16x port which is not a normal spot. You have to use Molex cables and connect all but one fan into the PSU itself which can be a pain. You also can't use your optical drive as it's designed for a laptop. You will need to buy a 5.25" drive or just use an external USB one if you want three HDDs inside. Third, the special power board in the X51 case allowed for everything to be crammed into one small space, but doesn't really work in another case, including another Micro ATX/ITX case. This case was custom built and wasn't meant to be transferred. There's also the issue of the Wifi antennas as they are designed like a laptop. Motherboards with wifi built in don't have these antenna cables normally and you have to hang them on a metal portion of the case to get a strong signal.
