The only two points I would warn you about is keeping an eye on are:
1.) Wear level, make sure you know what your getting into with regards of life span for a server machine. A lot of the manufacturers are reports 1.5 million hours of operation, but each manufacturer seems to be doing it differently. I personally stick to brands I like and Intel / WD. OCZ seems to have some nice stuff, but I've always been weary of their overall quality.
2.) Speeds / Stuttering. It seems with Win 7 much of the stuttering people experience with SSDs are now a non-problem, but I would look more into how nicely SSDs play with the various server OSes (especially the microsoft flavours).
