That might not be a good idea, SSD's can get pretty damned hot. This might be a better idea. It is only $1.50 and has free shipping.
Yeah, I know it's not exactly good, but it's right about where it should be and there's not much air circulation anyway. I'll try to find an adapter (and an extra SATA cable for my optical drive) at some point, though.
Update! So I got my EVGA nVidia 1080/Ti 11GB card about 4 months ago. I love this card! It soaks up anything I throw at it, all settings max, even though I have an older CPU. Heck, the fans don't even spin up unless I run a benchmarking suite. :D
