I don't have one, but if it uses an Intel chipset, and I'm pretty sure it does, it will handle SATA 3Gb/s drives fine. This is the case with my Dell Pentium 4 Optiplex GX270 desktop, which is based on an older Intel chipset. AFAIK, only older SiS and VIA chipsets (VIA VT6420, VT8237, VT8237R, VT8237R+, VT8237A, but VT8237S and VT6421A are OK) can't handle SATA 3Gb/s drives. Seagate drives can be configured for 1.5Gb/s or 3.0Gb/s maximum speed with a jumper, as can Western Digital desktop drives but not WD notebook drives (WD notebooks can't be changed), while Hitachi and Samsung drives require running a program to change their speed limits.
