My table (and the whole room) is a bit of a mess though, I really should clean...
You should start with some vacuuming, since this is a thread about input hardware I'll suggest Electrolux. A fine brand of vacuum cleaners, they don't take much space yet are still powerful for some serious vacuuming action (I know what you perverts might be thinking, but this is serious!!)
For taking out garbage, nothing does the job better than a standard plastic bag. Serious UT players prefer BLACK plastic, but it's just a matter of preference and personal taste.
Next, you should check for AwfulUnderwear, playing UT can get pretty intense, but you don't wanna be caught with a brown patch on your pants in the middle of the match - that would be a Humiliating Defeat straight away!
This brings us to the washing machine. Now this is really important. You can tell a good UT player by the washing machine he uses. For example you might think that skill is what makes Mordsspass a good UT player, nah you're completely wrong. The trick is in the washing machine - his is actually so loud I could hear it on TS (I'm not making this up, this happened, ask Mord) Therefore I'd suggest Whirlpool - it's a well respected brand the GUI is rich with options yet simple enough so that you can even let your girlfriend play with it from time to time.
So as you see we are not interested in pictures of your PC case, we are interested in photos of your vacuum cleaner, a package of plastic bags, washing machine and if you are brave enough, your underwear.
Bring it! and show us you are a true UT gamer.
