Antec 300? Blimey, that's the case my full sized ATX board and an FX 8350 are in. Quite a change from ITX
Not a brilliant case, but ISTR it was under £40 new so very good value . I was impressed enough that I got one to build my son's PC in as well.
Nice job you did of the hole in our ITX case though. Did it help with temperatures much?
