This is a SERVER not a desktop, the main issue will be due to the cooling systems it will be far too loud to use as a normal desktop. Trust me they're louder than you would expect.
Additionally, the site offering it for $31 will almost certainly not include the hard drive controllers or caddies, and even if it does they will likely be SAS (Serial attached SCSI) drives which are not the usual SATA or ATA drives. You'll end up spending more getting it to work than 2 or 3 regular desktops.
In summery nope.
