Hi. Ive just order a Black SN41G2 Shuttle for my little sister..and i know it sounds dumb but...does it mean i only have to buy an OEM CPU because the shuttle come with a heatsink? Also i've heard that these little shuttles can be noisy. I've heard the 40mm ADDA fan be mentioned for the PSU..i found it for £10..unfortunatly delivery was £8!...anyone know a cheaper alternative!! plus am i coreect in thinking i could replace the rear fan with a 80mm of my choice? like a papst or panaflo? Thanks for the help ppl.
