Adding hd, memory, and superdrive

Hey guys I ordered 3 gigs of ram, a 100 gig 7200 rpm hd, and a superdrive for my Mac Mini. I ordered it all from Other World Computing. My question is has anyone bought from them, and do you think that it will run hotter? I know that it will run a little hotter, but will it be to hot? Also I thought that the max memory for the Mini was 2 gigs. They sell a 3 gig kit (1g stick with a matched 2 gig stick).

Well since everyone looked but did not comment, I will tell you that I did the upgrade to 3 gigs ram, 100 gig hd @7200 rpm's and a superdrive. The Mini now runs a lot faster. I did a XBench test and scored 111, before I was in the low 90's. It does not seem to be running any hotter, which is what I was fearful of.
