Is there any way to add SSDs to my DL585 G2?

I've searched everywhere and the best info I can find is this document:

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=3219717&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c00305257-361%257CdocLocale%253Den%257CcalledBy%253DSearch_Result&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken#N1D436

It lists a few SSDs, like FK0032CAAZP, which may work, but I cannot find any real answers.

Will this old box support a standard PC style PCI-E card with SATA ports?
