I also agree, unless your going to upgrade to a larger chassis machine due to the need I would keep the 2310. If it has proven to you that it is reliable and it does what you need it to do then keep it. If you needed a larger machine consider a 1500 series. I dont think the 2410 or 2610 is that much of an improvement to soak the $4000 into, just my 2 cents.
