smaller hard drive than you had but faster processor with 1mb of l2 cahce and better graphics card. also you dont need sata cables as the mobo does come with them
ps you might want to add a floppy drive so add another £6,this is for linstalling windows on the sata drive (windows should load up without it but somtimes it dont) also if you can get your mate to spend an extra 50 quid i would definetly get 2 gigs of mem. games now love memory
