I'd appreciate some advice about which speakers to buy for my desk in my home office.

I moved my office recently and due to the way my desk is set up, the speaker cables for my Creative Inspire T3030 system (a 2.1 system that cost $50 new and has been out of production for a few years) are too short. One option is to buy a longer pair of RCA cables but, if I did, I'd be passing up a great opportunity to spend some $$ and get a new toy!

My sound source will be my computer, playing music from iTunes or using internet radio. My preferred listening level is low to moderate since I usually have to concentrate pretty heavily on my work (writing software).

From the quick research I've done, the Logitech Z2300 would be a great choice but I have some options.

Due to a recent upgrade to my home theater system, I have a spare Sony STR DE695 receiver and I have a Hsu sub woofer sitting next to my desk that's part of the home speaker system.

So, I'm thinking about using the Sony and the Hsu and buying a pair of inexpensive speakers to create a 2.1 system.

One question is how to hook up the Hsu. The input to the Hsu is RCA plug so would it be OK to get a Y cable to feed the sub from the home theater system on one cable and from the Sony on another cable?

Question two - what speakers would you wise folks recommend? I'd prefer to spend about $100 or $150 for the pair (this is a low budget adventure) and need a speaker that's not much more than 8" wide and 8" deep.

I'd sincerely appreciate your suggestions.
