recently my company is doing well in business, as more of clients are being served i am getting worried that i will run out of storage space in my server pc which is intel xeon w3550, intel dx58bp motherboard and 8 gigs of ddr3 ram nvidia quadro 600 and 1 tb wd hard disk. now my concern is that i will run out of storage space in a month or half, so what should i do should i upgrade this pc or build a new one and i need some good graphics handling capabilities as i work in CAD industry.
