You may want to look for a keyboard with a track ball they work a lot better and an RF transmiter instead of IR because the RF can be put anywere out of sight. The IR must be in line with the keyboard. I've seen several on ebay.
VIA EPIA V 1.1ghz
40gig 3.5" HDD
Slim Line DVD/CDRW
80w DC-DC Monex psu (fried 2, working on #3)
8" Datalux TS LCD
Sound Blaster USB
yeah infra red is kinda annoying, i have to either turn around and move it or hold the keyboard at an angle so the signal will deflect off the rear view mirror...wish i knew before and got one that operates with radio frequency instead.
