Hello! I would like to upgrade my Lenovo ThinkStation P300 (Lenovo) with an MSI GTX 970 (Amazon). This is my first upgrade, and I've been fighting with proprietary Lenovo configurations, so I would like to check my build before buying the parts.
According to the eXtreme Power Supply Calculator, I'll need about 600W of power (for later upgrading, mostly with 2x GTX 970 SLI). The upgrade to 750W was an extra $5 from Newegg, so I would like to get the decently reviewed Thermaltake SP-750PCBUS (Newegg). This appears to have all of the cables I will need (aside from the proprietary 14-pin Lenovo main pin, for which there is a converter [Amazon]). The Lenovo machine's standard PSU is the FSP450-50ERN.
The Lenovo case is 6.9" x 16.97" x 16.7" (175mm x 431mm x 424mm). I have measured it, and I believe that there is just enough room for the GTX 970 (10.9", 2 PCI slots). Note that I have a larger case available, a Gigabyte Cooler Master (after a quick search, I couldn't find the right case, but I can find its model number if requested), which is significantly larger than the current case. However, a) I don't know if the motherboard will mount onto it (I haven't checked), and b) I would prefer not to use it, as changing the case will void my warranty with Lenovo (though, changing out the PSU and graphics card might, as well, I haven't checked that either).
I have the following questions:
Question 1: According to the FSP450-50ERN's webpage, it is 5.9" (150mm) wide, while the Thermaltake is 6.3" (160mm) wide. Is this width difference significant/will this PSU fit in the current case?
Question 2: Will there be enough airflow in the case? It is a somewhat small. Will the available space be sufficient?
Question 2(b): Will the Lenovo motherboard mount in the Gigabyte case? Are motherboard mounts generally pretty standard, or is there a significant amount of variance?
Question 3: Can you think of anything that I have missed? I believe that I covered required power usage, power cable compatibility, and size compatibility. Should I be considering another area?
Thank you for reading, and for any help!
