This weekend I am mostly buying hard disks because I have decided that my 1U servers will look prettier with some stupid amount (about 1Tb) of disk in each. I'll probably start by just doing one though. Also there are IBM disks with a 3 year warranty (yes, a warranty that's >1 year still exists). This does mean that I have to sell a few more of my 1U and desktop systems to pay for the new disks. When people ask me what I do with N Tb of disk, I always say "porn". A worrying proportion of people believe me.
Also hunting for some gigabit cards for any of my switches, or a gigabit switch. Computer fairs are really really bad for me. Unfortunately I know that if I really go out looking for something, I can usually find someone who can sell me one. The backs of trucks are very good places to be.
