i have an acer pc, and its nice, its fast, and its quiet
(when you get all the un-necesery junk off the hard drive)
no overclocking like, but, its not a bad pc
dual core 3800+ and 2 gig of DDR2 for £380 ish
onboard graphics, but PCI-E slot
160 gig hard drive
media center edition, fairly decent in my opinion
comes with card reader
300W power suply n the usual junk
