I have a Dell R740 that I planned on turning in to a home lab but I ended up with a tower server instead. This was just a little too loud under load for my home office.
Dual Xeon Gold CPU
512GB RAM
2 Riser cards
1 4 port 5GB NIC
1 2 port 10GB SFP
12 HDD hot swappable slots, comes with 2 400GB drives and 2 480GB drives.
