Review on upHere 10pcs Black PCI Slot Cover Dust Filter Blanking Plate - Effective Protection for Hardware with Hard Steel Construction by David Carter

Great back panel for more airflow into the tower computer case and very well made. I really can't say anything bad about them. If I ever became a computer parts dealer I would definitely sell these items alongside regular unfinished metal colored ones like these. Enough said. They are worth the price I paid - not expensive and not cheap. Reasonable price and value for what I got. I installed 3 of these to cover up the 3 PCI slots that I no longer use on my motherboard, but I'm now considering putting the 56k modem and dual serial port PCI cards back into my build. A modem might come in handy if I ever use Windows fax and scan, and a dual serial card would also come in handy as I have a couple of old Cisco IOS routers that use a serial connection. That's why I put them in the tower in the first place. For those of you who just want the latest technology in their computers, this is great. but older people like me (48) still find the modem and serial card useful from time to time - and the cards themselves are not very expensive either - this opens up learning opportunities and learning a trade or activity that is really fun. and worth the trial and error that can occur during the learning process.
