sms server not running stand alone

We are looking at adding sms v2.0 to a Compaq ML370 dual P III @933 Mhz with 512 MB and SCSI Raid controller. This server runs Ghost 6.5.1 and we use it (exclusively) to image 600+ worksta. Have no experience with SMS or SQL, does anyone have any experiences with this type of configuration and problems we might expect to encounter? Is SMS likely to "hog" resources when we are deploying a new image? Would appreciate all relevant info anyone would care to share.
