Dell Inspiron 620 refurb: i5 3GHz, 6GB 1333MHz RAM, 1.5TB HDD, Windows 7, PCI wireless card, some crap Radeon VGA card... for £370 delivered.
Looks good to me. Not a gamer, but would be using CS5.5. Seems a better deal than a build-it-yourself bundle from Scan, although undoubtedly won't be as upgradeable in the future, which I'm not too bothered about tbh... Any better deals?
